An unpaved road, mostly downhill, runs along the crest of Bolinas Ridge, and from its heights you have magnificent views of the sparkling ocean, Tomales Bay, Point Reyes Peninsula, tree-covered ridges, deep canyons, oak-dotted hills, and distant peaks. On Bolinas Ridge, you travel through damp forests on soft and springy leaf duff; wind through tall chaparral on bare, rocky sandstone; and cross open, cattle-grazed grasslands. After descending to Lagunitas Creek, the shaded Cross Marin Trail is paved from Platform Bridge southeast through Samuel P. Taylor State Park. Weather and temperature vary: On Bolinas Ridge, long, exposed stretches of trail can be windy, hot, or foggy. For bikers, the Bolinas Ridge Trail can be bumpy and rutted. • From: Bolinas-Fairfax Road in Bolinas • To: State Park Entrance in Lagunitas • Length: 12.5 miles one-way to Samuel P. Taylor State Park; 12.2 miles one way to parking at Platform Bridge, Tocaloma; 11.1 miles one way to alternative trailhead at Olema Hill on Sir Francis Drake Boulevard; car shuttle possible. • Elevation Gain/Loss: 490 feet/1,800 feet one-way • Accessibility: Hikers, equestrians, and mountain bikers. Wheelchair users can access the 3-mile Cross Marin Trail. (This trail description is excerpted from the 2019 Guidebook.
