While certain mollusks escape predation by boring themselves into a soft rock, a crab such as a hermit crab may occupy an empty gastropod shell for protection. Near Abalone Point I saw a crab with a four-whorl turban-snail house wandering on the ground underneath the surface of the gently forward-swashing and backwashing shoreline water.

Getting thereFrom Stinson Beach, drive north on Highway 1. At the northern tip of Bolinas Lagoon, turn left onto Olema-Bolina Road and after 1.5 miles turn right onto Mesa Road. Drive to the Point Reyes Bird Observatory bend. Continue on the dirt road section of Mesa Road. Depending on your vehicle clearance and possible wash-outs, you may either want to look out for parking (and walk the dirt road) or continue the last one mile to the end, which is the trailhead for Coast Trail. Start out northbound on Coast Trail and find the signed Palomarin Beach Trail junction after less than a mile.
