Building More Fun Trails
We dig trails!
Building More Fun Trails
We build and improve multi-use trails across Boulder County. Our trail building events typically take place on weekday evenings and weekends from April to September of each year.
The City of Boulder, the County of Boulder, the U.S. Forest Service, and the City of Black Hawk recognize BMA as a committed partner thanks to our trail building expertise and the thousands of volunteer hours we donate.
Check out our full schedule of group trail building events. If you are looking for something more personalized, we can accommodate private trail building events for groups of five or more.
Upcoming Trail Building
OUR CURRENT PROJECTS
Lefthand OHV Managment Process
The US Forest Service Boulder Ranger District has began a management process to determine the future of Lefthand OHV. BMA participated in 4 stakeholder meetings in 2024 and 1 meeting in 2025 and will continue to advocate for advanced mountain biking experiences.
Betasso, Heil Valley Ranch & Hall Ranch
BMA continues to work with Boulder County Parks & Open Space to build and improve the trails at Betasso Preserve, Heil Valley Ranch and Hall Ranch. In 2021 and 2022 we improved the Picture Rock trail and 2023 work was completed on Wild Turkey. 2025 saw more work on Picture Rock, Ponderosa and Wapiti.
Marshall Mesa
BMA is partnering with the City of Boulder Mountain Parks and Open Space to improve the trails at Marshall Mesa. This year we rerouted and improved parts of Greenbelt Plateau and Coal Seam trails as well as maintenance to Doudy Draw.
Brainard Lake/Peaceful Valley
We’re tackling some long overdue trail repairs from the 2013 Flood on Middle St Vrain and Buchanan trails. We’ll be repairing walkways, adding drains and keeping these trails rugged for hikers and riders alike.
WEST MAGNOLIA
After years of partnership with the Boulder Ranger District, a $30,000 planning grant, and a ton of hard work, the US Forest Service (USFS) has approved an expansion of trails around the Nederland area that is on scale with Buffalo Creek. We are about 80% finished with Phase 1 (out of 4) of this project. This new system includes:
- 44+ miles of new trails
- 20+ miles of reclaimed user-created trails
- New restrooms and expanded parking
- Future potential to connect trails to Winter Park
- Ride from Nederland
- Improved signage and mapping
