Why it's important: 

This trail will connect to a biking trail constructed by Top of the Pines three years ago, expanding recreational opportunities on this public open space. Along the way, visitors will enjoy stunning views of the Sneffels Range, and future environmental education signs will highlight local ecology, forest health, landforms, and geology—helping visitors better understand and care for this special place.

Eligibility Requirements:   Ages 16+ 

Youth under 18 must be accompanied by an adult 21 or older on overnight projects. 

Project Difficulty:

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

General physical considerations for participating on this project (Some or all may apply): hiking to access work site while carrying tools, repetitive bending, lifting, digging, shoveling, moving soil and rocks. You’ll be working around a 6.5-7-hour day which requires some physical stamina, but you’ll always be encouraged to take breaks as needed.

Accessibility Factors:

Vehicle Accessibility: The final ~5 miles to the campground are on a maintained dirt road. High clearance is not required, and the road is accessible for 2WD vehicles. Please note that the road is very dark at night; we strongly encourage arriving before dark to make navigation easier.

Other Notes: The worksite begins about ¼ mile away from the camping area, an easy walk on a lightly used 2-track road. Indoor bathrooms with showers and flush toilets are available.

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 recreating patterns by helping to 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. 

General physical considerations for participating in this project (Some or all may apply): long hike to worksite with significant elevation gain; carrying project tools and materials to worksite; digging, shoveling, moving soil and rocks; repetitive bending, lifting, and walking; working at elevation; working and hiking on steep or uneven terrain.  

You can expect to bend, squat, lift heavy objects, dig, reach, stretch, lean, rotate, and engage many muscle groups, all at a high elevation. This project is not for the faint of heart!    

The hike from the campsite to the worksite is up to 2 miles. Volunteers may be hauling project materials up the trail to the worksite (logs for structures). 

Access Factors:  

Vehicle Access: Moderate vehicle clearance and AWD is require to get to the camping location. 

Other Notes: This is a remote project. There is no cell service at the campsite or worksite.

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.

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.

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.
