The Tamarancho Trails network is currently OPEN 03/25-27!
During seasonal rainfall up on Fairfax Ridge, the Tamarancho Trails may be closed intermittently to all mountain bike traffic. Heavy precipitation during January/February/March has kept the loop closed for long periods.
The Marin Council, BSA operates Camp Tamarancho high in the hills above the town of Fairfax. In partnership with the Friends of Tamarancho local volunteer group, we provide many miles of challenging and well-maintained mountain-biking trails around camp property, in addition to public access along the Marin County Open Space Preserve.
If you have questions or concerns about the trails, please email or call (415-454-1081) the Marin Council Service Center.
