Rockpile Beach & Tide Pools is the southern beach of Heisler Park in Laguna Beach, California. Rockpile Beach is in a south-facing cove with rocky outcroppings at each end. At high tide this narrow beach nearly disappears, but when the tide is out excellent tide pools are exposed. Surfing and tidepooling are the main activities here if you don’t count picnicking in the park above.
