Begin at Bolinas Ridge Trailhead on Sir Francis Drake Boulevard, about 1.1 miles east of Olema. Parking is limited roadside shoulder, roughly 300 feet paved and another 200 feet gravel. The south finish is on Bolinas-Fairfax Road, so settle return transport before setting out. The open northern pasture has little shade; bring enough water and sun protection for a long exposed walk. No food or water stop along the ridge was confirmed in the reviewed trail information. Winter and spring are the recommended seasons, with seasonal flowers including fetid adderstongue in February, checker lily in March and April, and Pacific trillium in April. Dogs are allowed on leash no longer than six feet, and bikes also use this corridor.
