Friends of Tamarancho

In the interest of our community Public Health to combat the spread of Corona Virus when using all Camp Tamarancho trails, PLEASE:

  • You must ride the loop in a clockwise direction;
  • Follow proper social distancing during this energetic activity;
  • Ride in control and be safe on the trails.

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 on camp property, in addition to public access for the Marin County Open Space Preserves.
