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. 

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.

Where You’ll Be: 

Spanning nearly 500,000 acres in southwest Colorado, the Weminuche Wilderness is three-quarters the size of Rhode Island and the state's largest Wilderness area. On this project, you'll be camped out in the front country of the Rio Grande National Forest near the Rio Grande Reservoir, and will hike into the neighboring Wilderness each day to complete project work.

The Weminuche (pronounced wim-in-ooch) spans the Continental Divide, North America's geological backbone, with its headwaters diverted to both the Pacific and Atlantic oceans. Eolus, Sunlight, and Windom peaks rise above 14,000 feet, while many others reach above 13,000 feet. With an average elevation of 10,000 feet above sea level, the Weminuche is rugged country, but its ecosystems are fragile. Volunteers will spend the weekend enjoying the breathtaking beauty of some of Colorado’s most picturesque alpine views during this project.

Nearest town: Creed, CO 81130

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

What You’ll Do: 

Volunteers will be in a group of 3-4 sawyers and will spend each day hiking the trails into the Weminuche Wilderness and logging out the trail on the way back down to basecamp.

Why crosscut saws?

Crosscut saws are a traditional tool that carry a long history of work on the land in our country, and have made a modern resurgence as the tool of choice for clearing fallen trees on trails in federally designated Wilderness areas, where workers cannot use mechanized equipment.

But it's not just about policy: using traditional tools allows us the opportunity to experience the quiet, solitude and characteristics of more remote areas, as well as become attuned to the characteristics of trees themselves.

Crosscut sawyers often talk about how they enjoy the experience of hearing the fibers of trees pop and crack as cuts are made. We welcome you to give crosscut sawing a try, not only to experience for yourself the use of a fun and powerful traditional tool, but to also allow yourself to spend time in nature in a way that perhaps you have not before. No experience is necessary to attend this project as a volunteer, a certified sawyer will be leading each cutting group.

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.  

Free campsites are available Thursday - Sunday nights, and volunteers are encouraged to arrive at base camp before 8 pm on Thursday if participating in the work on Friday.

Why It Matters: 

Wilderness trails on the Rio Grande National Forest are becoming increasingly inaccessible (and dangerous) to hikers and equestrians due to the falling dead Engelmann spruce trees in the area. The U.S. Forest Service cannot keep up with the demand for keeping the trails clear, making volunteers an increasingly critical asset to assist the Forest Service in keeping these Wilderness trails open and accessible to the public.

Eligibility Requirements:  Ages 18+ 

On this project, we need six B-certified crosscut sawyers. A-certified and non-certified volunteers will be able to cut under the supervision of B Sawyers. If you are certified, please include this in the comments of your registration.

Interested in getting certified? Visit our Training Calendar to view upcoming training opportunities.

Project Difficulty: 

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

Physical Considerations: This project will include hiking 4-5 miles each day up steep grade trails, at high elevation. Volunteers will need to carry all their supplies for the day and potentially a small tool for their group.  Working in the wilderness isn’t easy! Using a crosscut saw requires repeated cross body arm movement, often in a kneeling position. work will also include rolling or lifting heavy tree sections to clear them off the trail.

Access Factors: 

Vehicle Access: 2WD dirt road.

Other Notes: Tent camping OK. Car and Van camping OK. Large vehicles or tow-behinds may be accommodated, please contact Katie (katie@voc.org) to confirm availability. This project will be at 9500 ft. elevation. Vault toilets and potable water will be available at camp.

Where You’ll Be: 

On this project, you'll join us just outside of Granby to work on a rare trail system reserved for hikers and equestrians. Unlike many nearby trails, this landscape does not allow off-highway vehicles or mountain bikes, because the BLM has designated it as part of the Headwaters Extensive Recreation Management Area (ERMA), which aims to prioritize resource protection and low-impact recreation. 

Although impacted by the East Troublesome Wildfire in 2020, the area remains a meaningful destination for outdoor recreation. The hike to the worksite is moderately challenging and offers scenic views without wearing you out before the workday begins. This project is close to the town of Granby, Grand Lake, and the town of Hot Sulfur Springs.

What You’ll Do: 

In 2025, VOC and BLM partnered on a successful weekend project to install tread-stability structures along the first mile of the trail up to the hogback summit. On the west side of the Hogback, trail users have created a steep shortcut that abandons the original alignment and is unsafe and unsuitable for equestrian use. One of the primary goals of the Headwaters ERMA is to provide safe hiking and equestrian access for the general public.

VOC volunteers will help expand, define, and finish the reroute. This project offers a hands-on opportunity to learn introductory trail construction skills while contributing to a long-term solution.

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.

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: 

The Headwaters ERMA area has very few official access points and the Hogback Trail in its current condition is not sustainable or safe for users. Improvement of this trail will allow greater access by the public and other user groups to access this spectacular recreational opportunity in a more safe manner.  

The Hogback Trail and surrounding ERMA are located within the East Troublesome wildfire burn scar, where soil degradation and erosion remain ongoing concerns. The BLM's Kremmling Field Office is working to stabilize damaged trail segments and restore this area to a higher standard than before the fire. Your work directly supports those efforts.

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 to difficult; please check our difficulty rating criteria here for more details. 

General physical considerations for participating on this project. Some or all may apply: moderate lifting and tool use; digging, shoveling, moving soil and rocks; repetitive bending, lifting, and walking; may require hiking to access work site while carrying tools; you can expect to bend over, pick objects up, move rocks, carry tools, swing heavy tools, dig, and stretch.    

Access Factors:  

Vehicle Access: Parking is available and accessible to all vehicle types. The worksite will be a 5 minute drive from the campsite. 

Other Notes: The worksite will be a 1 mile hike from the trailhead. There is cell service at the site. While the project takes place below tree line, it is located within the East Troublesome burn scar so the area is very exposed.

A quick drive from Denver, Golden Gate Canyon State Park spans 12,000 acres, and features trails that pass through varied landscapes, including forests, rocky peaks, and aspen-lined meadows. The park attracts nearly 1 million visitors annually, offering opportunities for activities such as hiking, camping, and wildlife viewing. Expect beautiful scenery, rock formations, and the possibility of wildlife sightings, such as deer, elk, and various birds.

Nearest town: Golden, CO 80403

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

What You’ll Do: 

This trail project is all about building a more sustainable route in a popular part of the park. The focus is on enhancing sustainability, with tasks ranging from moderate to challenging, including: 

trail construction, rock wall building, and creating switchbacks for those seeking a technical challenge.

No trail building experience is required, just the desire to learn and give back to a well-loved State Park. 

Please bring your own lunch for the day! 

Why It Matters: 

High visitation at Golden Gate Canyon State Park means heavy wear on trails, especially along the Raccoon Trail near Reverend’s Ridge Campground and Panorama Point. This section is steep and has ongoing sustainability and safety challenges for visitors.

In 2020, volunteers began a long-term effort to close the unsustainable trail segment and build a safer, more sustainable reroute. By joining this project, you will be contributing to a six-year effort that improves trail safety and protects the park experience for years to come.

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.

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.

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

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. 

Eligibility Requirements: 

Ages 18+ 

Project Difficulty: 

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

Volunteers should expect some or all of the following physical activities: moderate lifting and tool use; digging, shoveling, and moving soil and rocks; repetitive bending, lifting, and walking; hiking to access the worksite while carrying tools or materials; and swinging hand tools.

The hike from the campsite to the worksite is 1.3 miles. A shuttle option will also be available. From the shuttle drop-off, the hike to the worksite is approximately 0.25 miles.

Access Factors:  

Vehicle Access: 2WD vehicles can easily access the campsite. Volunteers will carpool/shuttle to the project site from the campsite. High clearance vehicles can access the road from the campsite to the project site. 

Other Notes: Restroom facilities are available at the campsite. The project site is a 20-minute drive from the campsite.

Where You’ll Be: 

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:

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.

Please remember to bring your own lunch for the day. 

Why It Matters: 

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

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.

Canyons of the Ancients National Monument, spanning an impressive 176,000 acres, is a rugged, breathtaking landscape that holds the highest known density of archaeological sites in the United States, with 6,000 ancient sites, including cliff dwellings, villages, and captivating rock art. 

What you'll do: 

Join a small, dedicated group of 12 volunteers, per the national monument's visitor-use stipulations. Your efforts will focus on crucial seasonal maintenance closure tasks, such as social trail closure and restoration, drain cleaning, brushing, light tread work, and sign maintenance. Please keep in mind that temperatures can drop quite low in the evenings, so be prepared for potentially cold nights while 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's important: 

The Sand Canyon area within the monument is rich in cultural significance, hosting a high concentration of cultural sites. Designated as a Special Recreation Management Area, this area restricts public off-trail travel to preserve the integrity of its unique environment. By participating in closing social trails that lead to sensitive, non-public cultural sites, volunteers play a vital role in protecting and preserving the current character of these locations. This ensures that these sites can evolve naturally without the disruption of modern human interaction, safeguarding their cultural and historical significance for future generations.
