Upon reaching Rock Springs Road, prepare for the Tamarancho Camp trails. Make sure to purchase a $5 pass from Sunshine Bike Shop and grab a trail map. The trailhead is marked by the Alchemist Trail—a challenging segment that spirals towards the loop with a sudden ascent.
Loop around on the Goldman Trail, concluding at J8 with a scenic lookout. A quick follow of the signs leads to a spirited descent down the Broken Dam Trail. Hairpin turns and more await, so stay alert.
At intersection J5, a right turn onto the B-17 Extension Trail is a prelude to the White Hill Fire Road. Now out of the Tamarancho system, expect some quality double track filled with chunder and serious climbs.
The trail culminates on Cascade Canyon Road, known colloquially as Repack. This section is a roller-coaster of thrills, leading back to Bolinas Road, and ultimately, your starting point.
For a complete Marin biking experience that includes lush forests, vertiginous ridges, and a taste of mountain biking history, Tamarancho and Repack make for an unbeatable combo.
