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 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
There are no upcoming events at this time.
OUR CURRENT PROJECTS
BMA is teaming up with the Colorado Mountain Bike Association (COMBA) to help the City of Black Hawk develop a new trail system at Maryland Mountain! We are helping build four bike-only, downhill-only trails; a flow trail, one blue-rated, one blue/black rated and one double black!
BMA is partnering with the City of Boulder Mountain Parks and Open Space to improve the trails at Marshall Mesa. In 2017 and 2018, BMA improved over a mile of High Plains trail by taking it out of a drainage ditch and adding fun berms and bumps. In 2018, BMA also worked on Doudy Draw to eliminate trail braiding and added several A/B alternative rock lines. 2019’s work continued on Doudy Draw and Coal Seam, including adding a cow grate. Community Ditch got a new fun line in 2020. In 2021, we’ll put the finishing touches on Community Ditch and make improvements on Springbrook Loop.
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. This year we’ll be giving Betasso, Picture Rock and Hall Ranch some love and bike specific side features. Starting mid-August we’ll be working in the southern part of Heil Valley Ranch getting trails in the Calwood Fire area ready re-opening.
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
Brainard / South St.Vrain
In 2018, BMA fixed the eroded section on South Saint Vrain and turned it into a super fun gnarly armored downhill line. We’ll continue to work on trails in the Brainard area as the opportunity arises.
Tolland Ranch Trail
Boulder County Parks & Open Space began construction on this brand new 6.6 mile trail in 2020, and hopefully you’ll be riding high above Eldora Ski Resort by 2022! The Toll Trail will be an important connection between West Magnolia and Jenny Creek and is one of the last puzzle pieces of the Indian Peaks Traverse, a 66 mile multi-use trail from Boulder to Winter Park.
SCHEDULE A PRIVATE TRAIL BUILDING EVENT
We can schedule private volunteer trail building events for groups of 5 or more. We’ll work with your schedule and needs, let us know what you’re looking for!
