Fort Funston is located at the southern end of Ocean Beach in San Francisco. From southbound Highway 35, pass John Muir Drive, then take the first right (signed Fort Funston). Bear right and continue to the parking lot. From northbound Highway 35 (just north of the San Mateo County border), make a U-turn at John Muir Drive. Drive southbound and take the first right (signed Fort Funston). Bear right and continue to the parking lot. Drive to the very end of the lot, near the cliff and outhouses.

Access to the trail is in the southwestern corner of the parking lot. To reach the site, hike down the steps to the beach. The survey area is at the end of the trail. This is a steep, but well maintained, stairway and trail. Bring water.
