Chapter Service Areas

Chapter Regions

SWMMBA Chapters have areas which they primarily serve. While the organization as a whole serves over 20,000 square miles, our chapters focus their efforts in their local trails and improving their community.

Big Sky Chapter

Big Sky’s Chapter serves over 300 square miles in and around the unincorporated community of Big Sky, Montana. They have the responsibility to maintain trails like Mountain to Meadow, Porcupine-Buffalohorn, and Garnet Mountain. Additionally, they work heavily with Big Sky Community Organization to enhance bike access and bike parks across the community. They’ve branded themselves the Trail Dogs in honor of their legendary hot dog meals following trail work nights.

Bozeman Chapter

Bozeman’s Chapter serves over 500 square miles in and around the core urban center of the Gallatin Valley, Bozeman. They have the responsibility to maintain trails like Leverich Canyon, the Bangtail Divide, and Sypes Canyon. Additionally, they work alongside numerous other entities including Gallatin Valley Land Trust, the USFS, and the City of Bozeman to enhance mountain bike access to natural surface trails in the Gallatin Valley. They’ve branded themselves The Dirt Concern in a call back to SWMMBA’s original name.

Future Chapters

Chapters apply for their own service area, and cannot have overlapping service areas with other chapters of SWMMBA.
