Sierra Buttes Trail Stewardship’s Adventure Center is the pioneer of backcountry mountain biking in the Lost Sierra. We are avid mountain bikers, passionate about riding, hiking, exploring, building and maintaining the trails in this beautiful area.
Yuba Expeditions is an extension of the Sierra Buttes Trail Stewardship (SBTS) 501c3 non-profit dedicated to the maintenance and enhancement of trail systems.
