About San Diego-La Jolla Underwater Park Ecological Reserve

San Diego-La Jolla Underwater Park Ecological Reserve
 

The San Diego-La Jolla Underwater Park Ecological Reserve encompasses approximately 6 nautical square miles of protected marine habitat off the coast of La Jolla, California. Created to protect diverse underwater ecosystems and marine life, the park extends from La Jolla Shores beach to the waters surrounding the famous rocky reefs and kelp forests. It is managed by the California Department of Fish and Wildlife, serving to conserve an intricate underwater environment including vibrant kelp beds, rocky reefs, sand flats, and sea caves. The reserve supports a wide variety of marine species such as garibaldi (California’s state marine fish), leopard sharks, stingrays, sea stars, and multiple species of colorful reef fish. The area is also important for marine mammals including seals and sea lions that haul out onto nearby rocks. In addition to its ecological significance, the reserve is a world-renowned destination for snorkelers, scuba divers, and marine biologists keen to experience underwater biodiversity in a relatively accessible coastal setting. Visitors commonly explore the kelp forests and underwater caves, including the popular La Jolla Cave area, by boat or kayak, while also enjoying wildlife viewing from coastal trails and beaches. The park’s proximity to the urban environment of San Diego makes it popular for day trips and guided tours. The ecological reserve plays a critical role in marine conservation and public education about California’s ocean environments.
