Sierra Buttes Trail Stewardship

Formed in 2003, the Sierra Buttes Trail Stewardship (SBTS) is a volunteer-driven 501c3 non-profit dedicated to the maintenance and enhancement of trail systems.

Our focus is building sustainable recreation-based communities through stewardship, job creation, and world-class events. Providing quality outdoor experiences through trail construction and maintenance in the Lost Sierra.

Yuba Expeditions is operated by SBTS. We are a non-profit adventure center. All proceeds go right back into the trails you ride!
