Read more

Meet at the small, unmarked parking area near the top of the Jepson Trail, which is located just south of the entrance to Tomales Bay State Park on Pierce Point Road. To get there from central Marin, go out Sir Francis Drake Blvd. several miles past Inverness. At the fork in the road, bear right onto Pierce Point Road, and go approximately one mile to the parking area. If you see the entrance sign to Tomales Bay State Park, you’ve gone too far. Turn around and go back 200 yards.
