San Onofre State Beach Park Tide Pool

Map: San Diego Coastal Tide Pools

San Onofre State Beach Tide Pool can be reached by Basilone Road off Interstate 5 just north of the border checkpoint, a cobblestone tide pool area north of the campground. To the south and at the base of the bluffs below the campground, there is a small rocky area that consists of a fascinating formation of steeply tilted sedimentary rocks exposed at low tide. Hermit crabs are common, and in the mid-intertidal zone there is a dense mussel bed. With some luck, you may observe an Ochre Starfish.
