Things to do nearSan Diego - La Jolla Underwater Park

La Jolla Underwater Park was established in 1970 as one of California's first protected marine areas, encompassing roughly 6,000 acres of ocean floor that stretch from the shoreline out to federal waters. The reserve is divided into zones, including the San Diego-La Jolla Ecological Reserve, where all marine life is fully protected and collecting of any kind is prohibited. This legal protection has allowed the park to sustain thriving populations of California spiny lobster, octopus, moray eels, bat rays, and dozens of fish species. The towering kelp forests that anchor the ecosystem serve as nurseries for juvenile fish and hunting grounds for harbor seals that haul out on the rocks nearby.

Above the waterline, the rugged sandstone coastline is punctuated by a series of sea caves, most famously Sunny Jim Cave, which can be reached by a staircase cut through the cliff. Divers and snorkelers of varying experience levels find the park accessible, with calm entry points at La Jolla Shores and more challenging drift dives along the outer reefs for advanced visitors.

The surrounding neighborhood of La Jolla offers seafood restaurants, dive shops, and the Birch Aquarium at Scripps Institution of Oceanography, which provides excellent context for the marine life you will encounter in the reserve. La Jolla Underwater Park stands as a rare place where a world-class natural environment sits within easy reach of an urban coastline, making it one of the most rewarding marine destinations on the West Coast.
