From the top of Bolinas Ridge take in bird’s-eye views up and down the San Andreas Rift Zone. The fault divides Olema Valley, a lovely, undulating landscape reminiscent of England, that dips slowly down to the waters of Tomales Bay in the north, and Bolinas Lagoon in the south. The 10.5-mile Bolinas Ridge trail starts in Samuel Taylor Park.
- The Bolinas Ridge Trail, especially popular with mountain bikers, begins on the ridgeline east of Olema Valley, with parking off Sir Francis Drake Boulevard.
- The trail crosses rolling coastal rangeland, enters towering redwoods, and breaks into open chaparral before it reaches its southern trailhead at Alpine Road on Mount Tamalpais—offering views of Bolinas Lagoon, Tomales Bay, and the Pacific Ocean along the way.
