Yes, as the trails are on private property owned by the Marin Council of the Boy Scouts of America, you must purchase either a day pass or an annual pass. This helps support the ongoing development and maintenance of the trails.
The primary access point is the Camp Tamarancho Trailhead. Parking is typically available there, but it's always a good idea to arrive early, especially on busy days.
This loop is generally considered to be of a difficult grade, requiring good fitness and advanced riding skills. You'll encounter climbs, switchbacks, rock gardens, and descents. Trails like Wagon Wheel feature steep, challenging, and rocky singletrack, while the Alchemist Trail has an average grade of nearly 7% in some parts.
The terrain is incredibly diverse, traversing over 480 acres. You'll ride through redwood and oak-forested areas, open meadows, and past boulders. Expect predominantly singletrack, with sections ranging from smooth forest paths to technical features like rock gardens and roots. Breathtaking vistas are common throughout the ride.
The trails are enjoyable year-round, but spring and fall often offer the most pleasant conditions with mild temperatures and lush scenery. Summer can be warm, especially on exposed sections like Wagon Wheel, while winter can bring muddy conditions after heavy rains. Always check local weather before heading out.
No, dogs are generally not permitted on the private property of Camp Tamarancho where these trails are located. It's best to leave your furry friends at home for this ride.
The loop offers several highlights, including the Goldman Trail and Broken Dam Trail. A particularly notable feature is the Endor Flow Trail, the first flow trail built in the Bay Area, designed for pumping through humps and berms. You'll also find technical challenges like 'the rock' and various log rides.

You'll ride parts of the Bay Area Ridge Trail - 01 - North Bay, Goldman Trail, Wagon Wheel Trail, Broken Dam Trail, Blue Ridge Fire Road, Fairfax Ridge Road, B-17 Trail, Alchemist Trail, Dead Heifer Fire Road, Endor, Iron Springs Road, Serpentine Trail, B-17 Extension, Ridge Connector, Bent Bridge Cutoff Trail, Serpentine Trail Alternate, Creekside Fire Road, Burnt Tree Trail, White Hill Fire Road, Burnt Tree Fire Road, and Midway Lane.
