The Tomales Bay Trailhead is located on the east side of Tomales Bay. The Tomales Bay Trail is an easy 2.6 mile (4.1 km) roundtrip walk through pastureland in which cattle graze. Remember to close cattle gates behind you. Tomales Bay Trail leads past two stock ponds that teem with bird life. The trail climbs up and over a bluff with an incredible view of Tomales Bay to the edge of the restored Giacomini Wetlands.
Tomales Bay is a submerged rift of the San Andreas Fault. The trail is on the North American Plate. Inverness Ridge to the west runs along the eastern edge of the Pacific Plate.
While officially part of Golden Gate National Recreation Area, the Tomales Bay Trail is managed by Point Reyes National Seashore.
