Opportunities From: Volunteers for Outdoor Colorado

Where You’ll Be: 

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.

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.

Boulder's Open Space and Mountain Parks form a buffer around the city, helping to establish its own identity from neighboring communities. This project will take place in the Boulder Valley Ranch area, which offers access to many popular trails, including Sage, Eagle, Cobalt, and Left Hand.

What You'll Do:

Volunteers will help with the construction of the Hidden Valley Trail reroute. Work will include clearing vegetation to make way for the trail, digging and removing dirt to reach the proper trail level, and fine-tuning to create a smooth trail tread and a surface that drains properly.

Please bring your own lunch for the day.

Why It Matters:

This trail reroute is part of a larger trail improvement plan for the western Boulder Valley Ranch area north of the city. These projects aim to improve outdoor experiences, increase trail sustainability, and increase bicycling trail access while protecting wildlife and plant habitats in the area.

Eligibility Requirements:

Ages 14+ 

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

Physical Difficulty:

This project includes tasks at varying levels of difficulty, from easy to 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): 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.

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.

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.

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.
