Opportunities From: Volunteers for Outdoor Colorado

Why it's important: Training for Crew Leadership for trails is an essential part of building the capacity for stewardship in Colorado. This is a great way to take your environmental stewardship to the next level. As a Crew Leader, you will gain an understanding of trail terminology, methodology, and fundamentals of the functionality of a trail. Crew Leaders are an key component of projects; they follow the instructions of Technical Advisors and motivate a strong team of volunteers to complete that work.

What you'll learn: Through pre-workshop preparation online, classroom sessions, field exercises and role-playing, Crew Leader Trainees will learn the fundamentals of trail maintenance, construction, restoration, and erosion control. Trainees will also learn about tools and tool safety including tool identification, carrying, use, and storage. Trainees will learn about how to assess risks to avoid injury, individual learning styles, listening skills, and conflict and dispute management. A successful Crew Leader will be able to assess the individuals that make up the crew, understand motivational types and be able to effectively communicate the components of sustainable trail maintenance to their team. By the time the course concludes, Crew Leader Trainees will know how to motivate individuals to produce the desired end results in a safe manner, while utilizing the varied skills offered. All trainees will receive a crew leader manual, access to online modules, and a set of quick reference cards for a successful and fun experience.

What you'll learn:

Colorado’s bumble bees need your help! This summer, join our community of bumble bee loving volunteers across Colorado searching for and documenting these important pollinators.

This training will take place completely in the field and focuses on hands-on practice. Participants will learn how to safely net bumble bees, transfer them to vials, photograph them, and release them. We will also walk through how to complete the BBA data sheet. Please note that this is not a comprehensive training, volunteers should also watch a training webinar and review the Participant Handbook.

To get started and learn more about the project, visit BumbleBeeAtlas.org and sign up for the spring 2026 Webinar on Thursday, April 23.

Where you'll be:

This field training will take place in the San Luis Valley, which is four hours south of Denver. The training site will be located outside of Creede in an area known as Antelope Park. This location is about 25 minutes west of the town of Creede. VOC will not be hosting a basecamp for this training but dispersed camping options are available near the field site. More information will be provided via email to registered participants. 

Why it's important:

Bumble bees are charismatic and easily recognizable pollinators thanks to their large size, loud buzz, and distinctive color patterns. They play an incredibly important role in sustaining the health of our environment by pollinating flowers in natural and urban areas, and by contributing to successful harvests on farms.

Working together, Xerces' scientists, state and federal agency biologists, university scientists, and community scientists will be able to rapidly grow our understanding of bumble bees! Our teams of researchers will be able to use the new information to assess species distribution, population shifts, habitat associations and more. Additionally, the data will identify regions that are supporting healthy populations, as well as those in need of restoration or management, and highlight landscape features that are associated with bumble bee habitat. Understanding how species distributions have changed over time, in conjunction with habitat change, will help form accurate predictions as to what we should expect in the future, and aid in the design of effective conservation measures. ​

With your help, we can quickly cover the large regions of the country, collect scientific-quality data, and contribute to bumble bee conservation. Our efforts will help conservation biologists, restoration practitioners, and policy makers do a better job protecting, restoring, and managing effective habitat that support healthy bumble bee populations.

New to overnight projects with VOC? Learn more about what to expect here.

Where You’ll Be:  

State Forest State Park spans 71,000 acres of rugged Colorado wilderness, featuring dense forests, jagged peaks, and pristine alpine lakes. The American Lakes Trail, where you’ll be working, has grown in popularity due to its high-alpine scenery and access to three stunning lakes. It’s a sought-after destination for backpackers and serves as a gateway to Rocky Mountain National Park via Thunder Pass. In winter, part of the trail is groomed for snowmobiling.

What You’ll Do: 

Volunteers will help complete a long-term trail reroute on the American Lakes Trail by constructing new trail to replace an eroded section located on an old logging road. This hands-on work will improve trail sustainability and protect the surrounding landscape. VOC originally built much of this reroute trail in the early 2000s, and volunteers have recently returned over the past four seasons to address ongoing erosion issues. Since 2023, crews have completed maintenance and nearly 600 feet of new reroute, with 260 feet left before this section can open to the public. Join us to help finish this important reroute.

Enjoy breakfast and lunch on Friday, Saturday, and Sunday, with dinner on Friday and Saturday. Bring your own dinner on Thursday night, and enough snacks for the weekend.

As part of this three-day project, you will backpack 3.5 miles to base camp, where volunteers are encouraged to arrive before 8 pm on Thursday. Free campsites are available on Thursday, Friday, and Saturday nights.

Support This Project as a Crew Chef Helper! 

We provide full meals on our overnight projects to ensure volunteers are well-fed and ready for a day of volunteering — and we could use your help to make it happen! 

View this document to learn more about how to support and sign up. 

Why It Matters:  

Because the State Forest State Park is a popular destination in the summer and winter months, attracting hundreds of visitors each week during peak periods, many of these visitors use the trail system and camp or stay in nearby campgrounds or privately owned cabins. Many of these visitors will use the American Lakes Trail and will appreciate a much safer, more sustainable trail.

The trail reroute will improve the recreational experience for equestrians and mountain bikers by providing a safer, more comfortable route, free of a steep section with deep erosion channels and loose rock.

Where You’ll Be: 

The Gilsonite Trail is located in Grand County within the burn scar of the 2020 East Troublesome Fire. The project site is remote, about 50 minutes from downtown Granby. After the fire, many trail structures were damaged or destroyed, and flooding left sections of the trail swampy, muddy, and difficult to access.

Nearest Town: Granby, CO 80446

Exact location information will be shared with registered volunteers two weeks out from the project. 

What You’ll Do: 

Volunteers will be able to experience and help revitalize a trail post-fire. The Gilsonite Trail is a heavily used multi-use trail that provides an enjoyable experience for hikers, mountain bikers, and motorized users, keeping them off Stillwater Pass Road.  

In partnership with Headwaters Trails Alliance, volunteers will assist with a range of trail restoration tasks, including bridge and boardwalk replacement, turnpike construction, drainage work, and short reroutes. This work will help reopen sections of the trail that have been frequently closed since the 2020 fire. Some volunteers may also help move materials such as timber and rebar into the work area.

Adjacent to a fragile wetland and meadow, the work completed on this project will also keep users on the trail to prevent further trail widening, braiding, and wetland damage.  

Volunteers may need to assist with getting materials into the site (timber, rebar). 

VOC provides breakfast and lunch on Saturday and Sunday, and dinner on Saturday.

Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Why It Matters: 

This section of the trail runs alongside a fragile wetland and meadow. In its current condition, users often travel around muddy sections, which has led to trail widening and damage to the surrounding wetland. Replacing bridges, boardwalks, and turnpikes will help keep users on the designated trail and protect the nearby environment.

The Gilsonite Trail is also an important connector within the Stillwater Pass trail system. At nearly five miles long, it links the northern and southern portions of the system and provides a safer, more enjoyable single-track option than the nearby road. Volunteer work on this project will help restore a key connection in the trail system.

Whether you’re passionate about helping people and wildlife coexist, interested in gaining field research experience, or looking for a volunteer opportunity that’s less physically demanding, this project is for you. Join us to learn more about wildlife conservation efforts in the San Luis Valley!

New to overnight projects with VOC? Learn more about what to expect here.

Where You’ll Be: 

This multi-year volunteer effort takes place in the foothills of the San Juan Mountains on public lands near South Fork and Del Norte in Colorado’s San Luis Valley. The valley includes high-elevation wetlands, shrublands, and forests that support a wide range of wildlife, including sandhill cranes, bald eagles, elk, mule deer, coyotes, and beaver. Moose and wolves have also been documented in the area.

Nearest Town: South Fork, CO 81154

The exact project location will be shared with registered volunteers two weeks before the project.

What You'll Do:

Across the western United States, barbed wire fences are widely used to manage livestock, but they can create dangerous barriers for migrating wildlife such as elk and deer. This multi-phase project aims to reduce those impacts and improve wildlife movement through key winter range areas.

This year’s volunteer project focuses on Phase 2: Fence Surveys and Prioritization.

Volunteers will work in teams to survey existing fence lines and identify sections that pose the greatest barriers to wildlife movement. Using the Survey123 mobile app, teams will map fence segments and record details such as fence type, condition, wire height, sharp corners, flagging, smooth or barbed top wires, and the height of the bottom wire.

Volunteers will also document signs of wildlife, including tracks, trails, or direct sightings of animals.

At the end of the workday, Wildlands Network’s Western Program Director will share more about the organization’s work and its conservation efforts in the San Luis Valley.

Project Phases Overview:

Phase 1: Pre-field planning and logistics: This will involve calculating fence segment lengths, identifying road access for each fence segment, parking areas, and other logistics for field operations.  Phase 2: Fence surveys and prioritization (this project) Phase 3: Camera monitoring before and after fencing adjustments: Once we have identified the fence segments to be modified or removed using volunteer surveys, we will deploy 45 remote trail cameras along select fence lines for a migration season before and after the treatment.Phase 4: Fence modification and removal projects in 2027: Two additional volunteer projects will be hosted in 2027 where we will complete the modification and removals to the identified 15 miles of fence. Phase 5: Data processing and analysis: All photographs collected from trail cameras will be processed to analyze the effectiveness of the project and compare outcomes with pre-work documentation.Food and Camping:

Enjoy breakfast and lunch on Saturday and Sunday, with dinner on Saturday. Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Why It Matters: 

This project is a collaboration with Wildlands Network, an international nonprofit working to reconnect and restore wildlife movement across North America.

Each year, large herds migrate between summer and winter ranges in the San Luis Valley. Fences can disrupt these essential movements, increasing injury and mortality for wildlife. Fence improvements such as raising bottom wires, lowering top wires, and replacing barbed wire with smooth wire allow animals to cross more safely while still meeting land management needs.

The data collected during this project will help prioritize future fence modifications and removals, directly supporting wildlife migration in the region.

Eligibility Requirements: 

Ages 16+ 

For overnight projects, all youth under 18 must be accompanied by an adult aged 21 or older. 

Project Difficulty: 

This project is considered moderate; please check our difficulty rating criteria here for more details.

Physical Considerations: This project will include hiking 3-5 miles on uneven surfaces while using a mobile phone to complete surveys.

Access Factors: 

Vehicle Access: 2WD vehicles can access the campsite, but 4WD vehicles may be necessary to carpool to the worksites.

Other Notes: Tent camping OK. Car and Van camping OK. Large vehicles or tow-behinds OK. This project will be at 8400 ft. elevation. Portable toilets and potable water will be available at camp.

Where You’ll Be: 

This project is along the scenic Guanella Pass Byway, offering opportunities for wildlife viewing, hiking, mountain biking, and access to 4-wheel drive roads. The Abyss Trail trailhead is about 5 miles north of Grant from Hwy 285. This trail is one of the most heavily used trails in the Mt Evans Wilderness. With 10,000+ annual visitors, it leads hikers through famous fall colors and scenic landscapes. 

The trail's endpoint is Abyss Lake, which is nestled in a glacial cirque surrounded by Mount Bierstadt and Mount Blue Sky. The surrounding rocky slopes are home to lots of wildlife familiar to those who enjoy exploring the mountains, such as bighorn sheep and mountain goats.

Nearest Town: Grant, CO 80421

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You’ll Do: 

This project focuses on the lower three miles of the Abyss Trail, which follows an old logging road. The trail here is mostly flat, but the tread is very wide, often 10 to 25 feet across, and continues to spread into the surrounding forest. Because the soil is mostly loose, sandy material left by glaciers, rain and snowmelt easily wash it downhill toward nearby streams.

Volunteers will help slow this erosion by building a series of rock check dams across the trail. These low stone structures are designed to hold sand in place, reduce water flow, and stabilize the trail surface.

Tasks may include:

gathering and moving rock, shaping the trail surface, and placing stones by hand to form sturdy check dams.

No prior trail work experience is required, and tools and instruction will be provided on-site. On this project, you will be led by Steve West, one of our most experienced volunteers.

Steve has participated in more than 300 VOC projects since 1991 and brings decades of hands-on trail knowledge to the crew.

Please remember to bring your own lunch for the day. 

Why It Matters: 

The structures that volunteers construct will help control erosion, which will prevent widening of the already very exposed trail surface. Additionally, the structures will prevent large quantities of sand from migrating towards the Lake Fork Geneva Creek, which can cause issues for the flora and fauna of the creek. The South Platte Ranger District does not have the staff capacity to complete this work, making volunteer efforts critical to maintaining this trail.  

Eligibility Requirements: 

Ages 18+ 

Project Difficulty: 

This project is rated moderate to difficult. Please check our difficulty rating criteria here for more details. 

Physical Considerations: This project will involve hiking, bending to pick up heavy objects, stretching to reach items, and strenuous activities such as swinging tools.

Access Factors: 

Vehicle Access: The drive to the worksite is on a rough mountain road. While a cautious 2WD driver can make it, a 4WD vehicle is preferable. 

Other Notes: Nearby camping is available for volunteers who want to spend more time in the mountains. The trail is accessible via the Guanella Pass Byway, a well-known route connecting Highway 285 and I-70.

Where You’ll Be: 

Cal-Wood Education Center is nestled in the foothills above Boulder, near Jamestown. Cal-Wood's vision is to inspire a greater appreciation for the natural world; to offer environmental education to those who would not otherwise experience it; and to provide unique educational opportunities in a special mountain setting.

What You’ll Do: 

Volunteers will be working to help improve Cal-Wood Education Center's trail system, which has been degraded by dramatic increases in use, a flood in 2013, and the 2021 Calwood fire.

Tasks may include: 

clearing the trail corridor by trimming overgrown vegetation to keep paths open and safe, maintaining drainage by removing debris and improving water flow to prevent erosion, and repairing the tread to smooth and reinforce the trail surface for a safer and more durable path.

This is a great opportunity for new volunteers and anyone interested in learning more about trail restoration while enjoying a beautiful outdoor setting.

Please bring your own lunch for the day! 

Why It Matters: 

Cal-Wood relies on its trail system as an extension of the classroom. These trails give students and visitors safe access to forests, watersheds, and fire-affected landscapes where hands-on learning happens. Improving the trails makes it possible for Cal-Wood to expand outdoor education programs, reach more participants, and create positive first experiences for people who may be new to mountain environments.

Mount Democrat, at 14,148 feet and Colorado's 29th-highest peak, is part of the Mosquito Range, along with Mount Bross, Mount Cameron, and Mount Lincoln. The U.S. Forest Service recently acquired nearly 300 acres on Mt. Democrat, making the DeCaLiBron loop completely open to the public, for all to enjoy! Many underestimate this trail as an “easy” hike because of its high-elevation start, but it is rated a Class 2 climb. 

Nearest Town: Alma, CO 80424

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You’ll Do:  

Volunteers will assist with reconstructing portions of the trail above Kite Lake that have been widening and braiding at an excessive rate. Installing timber check steps will reduce soil loss and keep hikers on the trail. You'll work with our partners at Colorado Fourteeners Initiative (CFI) to install timber checks, delineate trails, and perform other maintenance tasks. The trailhead is at 12,000 ft of elevation (above tree line). Volunteers can expect to hike ~1.5 mi from the trailhead to the project site. 

VOC provides breakfast and lunch on Saturday and Sunday, and dinner on Saturday. Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Where You’ll Be: 

Tucked in the mountains west of Colorado Springs near Divide, Mueller State Park features beautiful views of forested ridges, historical cabins, and abundant wildlife including moose, bear, elk, and mule deer. While many of the park's trails trace back to the days of farming and cattle drives, they need restoration to enhance the overall hiking experience. As a volunteer, you'll be treated to free campsites, delicious meals prepared by our volunteer Crew Chefs, and the chance to explore this beautiful state park!   

Nearest Town: Divide, CO 80814

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You’ll Do: 

Before the VOC project weekend, park staff will use machinery to establish the initial alignment of the new Preachers Hollow Trail. Volunteers will then step in to do the hands-on finishing work.

Tasks may include:

cutting back slope, shaping and finishing the trail tread, placing natural materials to improve durability, and restoring sections of the old trail that will be closed.

This work will help bring the trail up to standards for hikers, mountain bikers, and horseback riders. The existing trail has steep grades, poor drainage, and more than 60 steps, which makes it difficult to maintain and inaccessible for some users. Volunteers will help improve drainage and trail layout so the new alignment sheds water properly and requires less maintenance over time. The result will be a safer, more sustainable loop near the Visitor Center that better supports a wide range of users.

Enjoy breakfast and lunch on Saturday and Sunday, with dinner on Saturday. Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Why It Matters: 

Realigning the trail will create a safer, more accessible route for all users. Horses will be able to travel the trail without risk from stairs, mountain bikers will be able to ride the full loop instead of dismounting, and hikers will benefit from a smoother, more intuitive trail experience. Improved drainage and a more sustainable layout will also reduce erosion, protect native vegetation, and lower long-term maintenance needs, helping the park provide a safer and more durable trail system for years to come.

Eligibility Requirements: 

Ages 14+ 

For overnight projects, all youth under 18 must be accompanied by an adult aged 21 or older. 

Project Difficulty:

Where You’ll Be: 

This project is along the scenic Guanella Pass Byway, offering opportunities for wildlife viewing, hiking, mountain biking, and access to 4-wheel drive roads. The Abyss Trail trailhead is about 5 miles north of Grant from Hwy 285. This trail is one of the most heavily used trails in the Mt Evans Wilderness. With 10,000+ annual visitors, it leads hikers through famous fall colors and scenic landscapes. 

The trail's endpoint is Abyss Lake, which is nestled in a glacial cirque surrounded by Mount Bierstadt and Mount Blue Sky. The surrounding rocky slopes are home to lots of wildlife familiar to those who enjoy exploring the mountains, such as bighorn sheep and mountain goats.

Nearest Town: Grant, CO 80421

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You’ll Do: 

This project focuses on the lower three miles of the Abyss Trail, which follows an old logging road. The trail here is mostly flat, but the tread is very wide, often 10 to 25 feet across, and continues to spread into the surrounding forest. Because the soil is mostly loose, sandy material left by glaciers, rain, and snowmelt easily wash downhill to nearby streams.

Volunteers will help slow this erosion by building a series of rock check dams across the trail. These low stone structures are designed to hold sand in place, reduce water flow, and stabilize the trail surface.

Tasks may include:

gathering and moving rock, shaping the trail surface, and placing stones by hand to form sturdy check dams.

No prior trail work experience is required, and tools and instruction will be provided on-site. On this project, you will be led by Steve West, one of our most experienced volunteers.

Steve has participated in more than 300 VOC projects since 1991 and brings decades of hands-on trail knowledge to the crew.

Where You’ll Be: 

Signature Bluffs Natural Area is a riparian and wetland natural area along the Cache la Poudre River with soft-surface trails, cottonwood stands, cattail marshes, and a pond where fishing is allowed with a valid Colorado license. The site is well known for wildlife and bird watching and connects directly with the Poudre River Trail for extended hiking or biking. The exact meeting location will be shared via email at least seven days prior to the project. 

What You’ll Do:  

Volunteers will help improve visitor access while protecting sensitive habitat at Signature Bluffs. Work will focus on closing and revegitating informal social trails around the lake to reduce habitat disturbance and support native vegetation recovery.

Volunteers will also improve the designated primitive trail by widening and defining it, creating a safer and more welcoming route to fishing access points. This project is a good fit for new volunteers and anyone interested in learning more about trail restoration.

Please bring your own lunch for the day.

Why It Matters: 

Informal trails can fragment habitat and impact wildlife and native plants. By restoring these areas and improving designated trails, this project helps protect sensitive ecosystems while guiding visitors to enjoy the landscape in a sustainable way. The work completed at Signature Bluffs supports long-term habitat health, safer recreation, and a better experience for everyone who uses the area. 

Eligibility Requirements:  

Ages 12+

Youth under 16 must be accompanied by an adult aged 21 or older. 

Project Difficulty:  

This project is considered easy to moderate; please check our difficulty rating criteria here for more details

Work takes place outdoors with exposure to sun, weather, and insects such as bees and wasps. Tasks may include carrying, hauling, and placing heavy materials like logs, branches, rocks, and fencing, as well as digging, shoveling, and moving soil and rocks. Some work will take place near water, where footing may be muddy or slippery.

This is a 6.5 to 7 hour workday that requires some physical stamina, and volunteers are always encouraged to take breaks as needed.

Access Factors:   

Vehicle Access:  No vehicle restrictions – 2WD accessible  

Other Notes: Cell service may be spotty in this area.

Where you'll be: 

This project takes place in the Mount Evans Wilderness, located within Arapaho and Pike National Forests about 30 miles west of Denver. The wilderness spans more than 74,000 acres and is known for its high-elevation meadows, wide-open views, and wildlife such as bighorn sheep.

What you'll do:  

This weekday project is a great opportunity for volunteers ages 12 and up to spend time outdoors while supporting meadow restoration. Volunteers will hike approximately 1.4 miles on the Captain Mountain Trail to reach the work site. Working in a group of about 20 people, volunteers will remove mature thistle blossoms, while staff follow up with a targeted chemical treatment that will be applied to the plants. If time allows, the group will also help identify musk thistle rosettes and Canada thistle to support ongoing management efforts.

Why it's important:  

Maintaining healthy native flora is essential for the local ecosystem, and, left unchecked, the invasive thistles will take over the area and out-compete native plants to create a monoculture. 

Eligibility Requirements:  

Ages 12+ 

Youth under 16 must be accompanied by an adult 21 or older.    

Project Difficulty:

This project is considered easy to moderate in nature. Please check our difficulty rating criteria here for more details.

Physical Considerations: Pulling or cutting vegetation; working on uneven, sloped, or rough terrain; bending and stooping for long periods; carrying and hauling vegetation.

Access Factors:  

Vehicle Accessibility: The last ~4 miles of the road (on Upper Bear Creek Rd) are not paved but accessible to all vehicles. All volunteers will meet at the lower parking lot and carpool (~2 mi) to the project site.

Other Notes: Restrooms available only at the main parking lot.

Where You’ll Be: 

Nestled in the Upper Yampa River Basin, about 1.5 hours northwest of Steamboat Springs, California Park is a high-elevation meadow known for its stunning views, vibrant wildflowers, and critical role in supporting the Upper Yampa River Basin and Colorado River Basin. This area is vital for water quality and watershed health, making it a key site for restoration efforts.   

The campsite is surrounded by beautiful, rolling, forested hills. While the site is remote, it offers a quiet setting that many people would not otherwise have a reason to visit.

You'll also likely travel through Steamboat Springs, so you have the chance to tack on a trip to nearby hot springs on the front or back end of the project!

What You’ll Do: 

In year two of this project, help restore this fragile meadow ecosystem by building erosion prevention structures, like Zeedyks and Zuni Bowls, primarily using rocks. These structures are proven, cost-effective methods to slow erosion and restore streams. Tasks will include hiking, moving large rocks, and digging to place them into position.

It’s challenging but rewarding work, you’ll leave with the satisfaction knowing that you've slowed erosion and helped revive a critical part of this watershed! This project will be completed in partnership with National Forest Foundation, Yampa Valley Sustainability Council, and the US Forest Service

Join us at Majestic View Nature Center (MVNC), a nonprofit that serves the Arvada community by offering a diverse array of public programming designed to foster connections with the natural world. From creative nature art sessions to engaging conservation presentations, MVNC ensures that individuals of all ages in the community can explore their connection with nature. You may be interested in visiting the nature center's exhibitions yourself!

Nearest Town: Arvada, CO

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You’ll Do:

Volunteers will get hands-on experience with stream and habitat restoration by helping build simple rock-and-wood structures (such as one-rock dams, Zuni bowls, and wicker weirs) that slow water flow, capture sediment, and support native plant recovery. Volunteers will move and place rocks, weave woody materials, and help stabilize the stream channel. No experience needed.

Please bring your own lunch for the day.

Why It Matters:

When streams erode, water moves through the landscape too quickly, washing soil away and leaving streambanks dry and unstable. The structures volunteers will build will slow water down, allowing sediment to settle and moisture to soak into the ground instead of rushing downstream.

Holding water in the landscape supports native plants, which stabilize streambanks and create habitat for birds, insects, amphibians, and other wildlife. Over time, this leads to healthier ecosystems, improved water quality, and greater resilience to drought and flooding.

Eligibility Requirements:

Ages 16+ 

Physical Difficulty:

This project includes tasks ranging from moderate to difficult. Please check our difficulty rating criteria here for more details.

General physical considerations for participating in this project (Some or all may apply): lifting and moving large rocks, digging holes, and placing rocks.

Access Factors:

Vehicle Access: 2WD accessible

Other Notes: There will be about a 1/4 mile hike from the parking lot to the work site.

Where You’ll Be: 

Sand Creek Park is located in Aurora and co-managed by the City of Aurora and the Sand Creek Greenway Regional Partnership. Bicyclists, walkers, runners, picnickers, school groups, and community groups enjoy this 85-acre park and the Sand Creek that runs through it. The Greenway itself serves as one of the few green spaces that neighboring communities in Aurora, Commerce City, and NE Denver can easily access.

What You’ll Do: 

City of Aurora and Sand Creek Regional Greenway Partnership staff will teach you how to identify invasive Phragmites. After learning how to identify this plant, you'll spread out to clip and bag seed heads of the invasive grasses.

Phragmites grow along the water’s edge and into the water. If you have your own rubber boots or waders, you are encouraged to bring them to access the harder-to-reach plants. If not, you can stay on the shoreline and clip from there. 

Please bring your own lunch for the day! 

Why It Matters: 

Invasive plants out-compete native species for resources, thereby harming wildlife and the entire ecosystem. By carefully collecting the plants' seed heads, you will help control the further spread of this invasive species. Removing these grasses will allow for native plants to clean our water, prevent severe erosion, and provide enhanced wildlife habitat, all while maintaining access for local communities to enjoy this well-used green space.

Eligibility Requirements: 

Ages 12+   

Youth under 16 must be accompanied by an adult aged 21 or older.   

Project Difficulty:

Holding water in the landscape supports native plants, which stabilize streambanks and create habitat for birds, insects, amphibians, and other wildlife. Over time, this leads to healthier ecosystems, improved water quality, and greater resilience to drought and flooding.

Eligibility Requirements:

Ages 16+ 

Physical Difficulty:

This project includes tasks ranging from moderate to difficult. Please check our difficulty rating criteria here for more details.

General physical considerations for participating in this project (Some or all may apply): lifting and moving large rocks, digging holes, and placing rocks.

Access Factors:

Vehicle Access: 2WD accessible

Other Notes: There will be about a 1/4 mile hike from the parking lot to the work site.

If you enjoy projects that include components of rock work, you can view similar projects here.

Where You’ll Be:

You will be monitoring butterflies near Deckers, Colorado. This will take place in Pike National Forest along the South Platte River watershed. This is a critical ecosystem for the butterfly sub-species Hesperia leonardus montana.

Camping may be available for those who are interested in attending more than one day of the project. We will reach out 1 month before the project with more instructions on how to reserve a camping spot.

What You’ll Do:

Volunteers are needed to assist in monitoring the threatened butterfly subspecies, the Pawnee montane skipper. Monitoring will involve using binoculars to identify and record the number and gender of skipper butterflies, along with information on nearby host plants and trees. Please bring your own lunch for the day!

This butterfly species is only out and about when conditions are warm and dry. The project schedule is highly weather-dependent, but volunteers should plan to be on site for the full day.

Why It Matters:

The Pawnee montane skipper is a species with a narrow distribution that is endemic (native) to Colorado. Fire suppression, dam and reservoir development, and climate change are all threats to the persistence and recovery of this federally threatened species.

Eligibility Requirements:

Ages 18+

Project Difficulty:

This project is considered difficult and a great opportunity for volunteers looking for a challenge. Please check our difficulty rating criteria here for more details.

If a volunteer cannot commit to the full surveying time for the day, this could affect the integrity of the data, the safety of the group, and the project as a whole.

Physical Considerations: Volunteers can expect to hike off-trail through steep terrain for up to 5 miles round-trip. Elevation ranges from 6,000 ft to 8,000 ft. At this time of year, the weather is usually cool in the mornings but quickly warms to the high 80s or low 90s (though please check the weather in advance). This project is not for the faint of heart!

Access Factors:

Vehicle Access: No 4WD is required to reach the project area or sample sites; good tires are recommended to avoid flats on gravel roads. Beyond the initial meeting spot, we will aim to use agency vehicles whenever possible to minimize personal vehicle use.

Other Notes: Cell coverage in the area is minimal and varies by cell service provider.

Where You’ll Be: 

This project will take place at Cub Creek Park in Evergreen, Colorado, part of the historic Denver Mountain Parks system. Surrounded by ponderosa pine forests and mountain scenery in the foothills west of Denver, the park provides important wildlife habitat, recreation opportunities, and natural open space for the community.

What You’ll Do: 

The project area will most likely be steep and rocky, which makes chainsaws and hand saw work the most viable solutions for fuels management. For this project, we are looking for saywer and swamper volunteers. Sawyers must be certified. Swampers will build burn piles that the city will burn later in the season when the conditions are safe for this activity.

Please bring your own lunch for the day! 

Why It Matters: 

The fuels management work will, first and foremost, assist with the local fire mitigation plan and implementation recommendations by the Community Wildfire Protection Plan. By removing fuels in the park, VOC volunteers will make the communities surrounding the park safer and more resilient to wildfire. VOC’s work will also help protect nearby homes, businesses, schools, infrastructure, and evacuation routes. 

Eligibility Requirements: 

Ages 18+  

On this project, we need a mix of A and B certified Chainsaw Sawyers. If you are certified, please include this in the Comments of your registration and send your certificate to the project manager. ALL SAWYERS MUST HOLD A CURRENT FIRST AID AND CPR CERTIFICATION IN ORDER TO OPERATE A SAW. Want to get certified? Visit our Training Calendar for upcoming training opportunities.

Project Difficulty: 

This project is considered difficult. Please check our difficulty rating criteria here for more details. 

Physical Considerations:  

Expect physically demanding work, including moving heavy materials (such as logs and branches) and working on uneven terrain. Volunteers will hike on uneven terrain to find a good working area that is a sufficient distance from other active sawyers.

Access Factors: 

Vehicle Access:  Volunteers will be able to drive and park close to the worksite

If you enjoy chainsaw projects, either as a certified sawyer or a support volunteer, you can view similar projects here.

Where You'll Be:

The Southern Plains Land Trust was founded in 1998 to protect and restore shortgrass prairie across the Southern Great Plains. Today, SPLT stewards more than 60,000 acres of protected land in southeast Colorado, where they focus on ecological restoration, reintroducing keystone species like black-tailed prairie dogs and American bison, and connecting local communities to the land through education and outreach.

This project takes place at the Purgatoire River Preserve, a newly protected 493-acre property in Bent County. Acquired by SPLT in January 2025, the Preserve is intended to protect the Boggsville National Historic Site, provide public access to the Purgatoire River, and create a new outdoor recreation resource for Las Animas and surrounding communities.

Nearest town: Las Animas

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You'll Do: 

Volunteers will help build a new natural surface trail on the Purgatoire River Preserve, just south of Las Animas. This trail segment will provide river access and connect to an existing trail at Boggsville.

Trail work will include construction of natural surface trail in a flat landscape.

The goal of this project is to complete a segment of trail that provides access to the Purgatoire River and connects to an existing trail in Boggsville. This is foundational work on a brand-new preserve, and volunteers will play a key role in creating the first public trail access at this site.

VOC provides breakfast and lunch on Saturday and Sunday, and dinner on Saturday.

Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Where You'll Be:

William Frederick Hayden Park sits atop Green Mountain, a prominent open space in the heart of Lakewood and one of the most well-loved urban parks on the west side of the Denver metro area. Originally donated by the Hayden family in 1972, the park now spans more than 2,400 acres, making it Lakewood’s second largest park.

Its extensive network of multi-use trails draws more than 250,000 visitors each year, offering an easy escape from the city for hikers, trail runners, mountain bikers, and families. From the 6,800-foot summit, visitors enjoy wide views of both downtown Denver to the east and the Front Range to the west, while the park also provides important habitat for wildlife including mule deer, elk, and great horned owls.

The specific location will be shared with all registered volunteers 2 weeks before the project. 

What You'll Do:

After a major trail reroute in 2018, some hikers have been cutting switchbacks along the middle section of the Rooney Valley Trail to avoid bike traffic and take a more direct route. We will be responding to these hikers recreating patters helping build rock steps that create a designated pedestrian bypass.

This allows hikers a more direct route while keeping the longer, gently graded switchbacks intact for wheeled trail users. Volunteers will assist with the construction of rock steps.

Please bring your own lunch for the day.

Why it Matters: 

The existing social trail follows a steep slope and is not sustainable. Continued use degrades wildlife habitat and spreads noxious weeds that threaten the native shortgrass prairie. Building this bypass helps protect sensitive habitat, reduces erosion, and supports the long-term goal of making every trail in William Frederick Hayden Park both sustainable and enjoyable.

Where You’ll Be: 

Mt. Sneffels, located in Ouray, CO, is accessible through Yankee Boy Basin. This basin is home to fields of wildflowers and wildlife and leads up to one of the most beautiful fourteeners in the state. Nestled in the San Juan Mountains, Mt. Sneffels receives about 5,000-7,000 visitors annually, which is relatively low but has some of the worst conditions of the five major ranges, according to a recent report card procured by Colorado Fourteeners Initiative. 

Nearest town: Ouray, CO 81432

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You’ll Do: 

At Mt. Sneffels, several large tundra beds are being undercut due to foot traffic. As soil erodes from beneath plant life, this delicate vegetation dies.

In partnership with Colorado Fourteeners Initiative, volunteers will help construct retaining structures and delineate the trail to ensure the continued health of this important alpine environment. Improvements such as installing tundra support walls and rock check steps will stabilize the footpath, allowing hikers to stay on the route and preventing widening of the existing trail. 

Enjoy breakfast and lunch on Saturday and Sunday, with dinner on Saturday. Bring your own dinner on Friday night, and enough snacks for the weekend.  

Free campsites are available on Friday and Saturday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Friday.

Why It Matters: 

Colorado’s 54 fourteeners (peaks over 14,000 feet in elevation) see over 300,000 hikers and climbers each year – all of whom are traveling through the alpine tundra ecosystem. This ecosystem thrives in an environment of high winds, short growing seasons, and cold winters, but is very easily damaged by foot traffic and erosion. Construction and maintenance of hiking trails on fourteeners prevent impacts to the sensitive plants and wildlife, and restoration projects repair areas that have already been damaged. 

Eligibility Requirements: 

Ages 18+ 

Project Difficulty: 

This project is considered difficult; please check our difficulty rating criteria here for more details.

Where You’ll Be: 

Button Rock Preserve is a 3,000-acre nature preserve outside of Lyons that protects the primary drinking water source for more than 110,000 Boulder County residents. The area supports passive recreation like hiking, rock climbing, and fishing along North St. Vrain Creek, Longmont Reservoir, and Ralph Price Reservoir. Volunteers will work in a scenic, high-use recreation area while helping care for an important community resource.

Nearest town: Lyons

The specific location will be shared with all registered volunteers 2 weeks before the project.

What You’ll Do: 

Volunteers will support trail restoration work along the South Cove Trail at Button Rock Preserve.

The focus is on approximately 720 feet of trail that is severely undercut and collapsing into the reservoir, creating safety, access, and water quality concerns. Tasks may include defining trail tread, improving drainage for water to flow off the trail, building small reroutes, and assisting with retaining wall construction to stabilize eroding sections. This is a technical trail project in steep terrain and requires focused, hands-on work.

Why It Matters: 

South Cove Trail’s condition directly affects visitor safety, water quality, and access within a high-use recreation area. Restoring this trail segment will reduce erosion into the reservoir, improve safety for hikers, and support long-term stewardship and infrastructure resilience at Button Rock Preserve.

Where You'll Be:

Pence Park is a beautiful, quiet respite just thirty minutes from Denver. Pence Park's wide variety of trails has become a popular destination for hikers and bikers along the Front Range. Mountain bikers flock from miles around to ride from Lair O' the Bear to Pence Park, a scenic 13 miles. Pence Park's unique array of wildlife includes bald eagles, Mexican spotted owls, the Preble's jumping mouse, and the Townsend's big eared bat. Exact meeting location will be shared via email at least 7 days prior to the project.

What You'll Do:

Volunteers will help with much-needed trail maintenance at the park, just a short trip from the Denver metro area.

Tasks may include:

clearing the trail corridor by trimming overgrown vegetation to keep paths open and safe, maintaining drainage by removing debris and improving water flow to prevent erosion, and repairing the tread to smooth and reinforce the trail surface for a safer and more durable path.

This is a great opportunity for new volunteers and anyone interested in learning more about trail restoration while enjoying a beautiful outdoor setting.

Why It Matters:

Trail maintenance matters from an ecological and environmental standpoint because it ensures a safe and sustainable route for people to use, which keeps the surrounding habitat safe and minimizes the human impacts on flora and fauna, especially in high-use areas like Pence Park.

Eligibility Requirements:

Ages 16+

Project Difficulty:

This project is considered moderate, please check our difficulty rating criteria, here, for more details.

Physical Considerations:   You can expect to bend over, pick objects up, move rocks, carry tools, swing heavy tools, dig, and stretch. 

Access Factors: 

Vehicle Access: No vehicle restrictions – 2WD accessible 

Other Notes: Cell service may be spotty in this area.

Where You'll Be:

Parkfield Lake Park is a mixed-use park in the Montbello neighborhood of Denver. It is home to the Montbello Recreation Center, athletic fields, trails, a lake, and open space, and is surrounded by dense housing. The park is highly valued by the Montbello Community, and the trails are heavily used around the lake and in the open space areas.

What You'll Do:

Volunteers will be constructing timber steps on a trail at Parkfield Lake Park. This project will be critical to restore a degraded and eroded trail, making it safer for park users, increasing access, improving aesthetics, and reducing maintenance strain on Parks staff.

Please bring your own lunch for the day.

Why it Matters:

The timber steps will improve safety, mitigate erosion, and reduce the expansion of social trails into the natural landscape.

Eligibility Requirements:

Ages 18+

Physical Difficulty:

This project is considered moderate to difficult; please check our difficulty rating criteria here for more details.

Physical Considerations: The project tasks can include digging into the hillside, lifting and placing lumber, and lifting and placing gravel on a steep slope. If you would like to participate in this event but the primary tasks do not suit you, we can accommodate volunteers removing weeds.

Access Factors:

Vehicle Access: 2WD accessible

Other Notes: Restrooms will be available on site. It is a 5-minute walk on a paved trail from the parking lot to the project site.

Where You'll Be: 

Roxborough State Park, south of Littleton, is a 4,000-acre park designated as both a Colorado Natural Area and a National Natural Landmark. Known for its red rock formations, diverse plant communities, and abundant wildlife, the park welcomes around 100,000 visitors each year. A network of trails allows people to experience the foothills while protecting sensitive natural resources.

What You'll Do:

Heavy rainstorms and high trail use have worn down the drainage features on one of the park’s trails.

A trail's worst enemy is water. When it is not redirected properly, it can wash away soil, create ruts, and make trails unsafe or hard to use.

Volunteers will help restore and build simple water-diversion features, such as low trail crossings, shallow channels, and drains, that guide rainwater off the trail and into the surrounding drainage areas.

This work helps keep water from flowing straight down the trail, reducing erosion and making the trail more durable during future storms. Please bring your own lunch for the day.

Why It Matters:

With new residential developments in the area, the number of visitors to the park will only increase. Improving the trails now would allow us to mitigate the impact of a future large increase in trail users. In addition, fixing the drainage along this trail will prevent damage from future rainstorms. This will allow staff to focus on improving other trails rather than just repairing damage. The work from this project will improve the visitor experience, enable more family use with strollers and mobility devices for those with mobility impairments, and allow park staff to offer tours to those who cannot hike the trail.

Eligibility Requirements:

Ages 16+

Project Difficulty:

This project is considered moderate; please check our difficulty rating criteria here for more details.
