About Santa Catalina Island Marine Protected Areas

Santa Catalina Island Marine Protected Areas encompass coastal waters around Catalina Island, offering rich underwater habitats and protection for diverse marine life. These areas are popular for snorkeling, diving, and wildlife observation.

Wilderness Landscape & Natural Heritage

The Santa Catalina Island Marine Protected Areas (MPAs) are a collection of state-designated zones surrounding Catalina Island, located off the southern California coast. These protected waters encompass kelp forests, rocky reefs, sandy bottoms, and offshore rock formations that provide critical habitat for a wide variety of marine species including fishes, invertebrates, and marine mammals. The MPAs serve the dual purpose of conserving biodiversity and supporting recreational activities such as diving, snorkeling, kayaking, and fishing within regulated guidelines. Historically, the island and surrounding ocean have long been significant to indigenous peoples and later became a hub for fishing, tourism, and conservation efforts. The MPAs help maintain ecosystem health by limiting certain types of extraction and providing refuge areas where marine life can thrive unimpeded. Key recreation opportunities include visiting the renowned Casino Point Dive Park, exploring the shipwrecks off Catalina’s coast, and spotting pinnipeds and Garibaldi fish in clear waters. The underwater kelp forests feature prominently and constitute some of the best-preserved coastal marine habitats in Southern California. Visitors appreciate the calm, clear waters and exceptional visibility, making Santa Catalina Island MPAs a top destination for marine wildlife enthusiasts and eco-tourists alike. In addition to ecological benefits, these MPAs also contribute to local economies through sustainable tourism and improved fisheries management.
