About Catalina Island Marine Protected Area

Catalina Island Marine Protected Area (MPA) preserves diverse coastal and marine ecosystems around Santa Catalina Island, offering rich opportunities for snorkeling, diving, and wildlife observation.

Wilderness Landscape & Natural Heritage

Located off the coast of Southern California, Catalina Island Marine Protected Area encompasses extensive kelp forests, rocky reefs, and sandy bottoms that provide critical habitat for a wide range of marine species. This MPA includes areas surrounding Catalina Island, part of the Channel Islands chain, protecting over 36 square miles of ocean environment from certain extractive activities. The protected waters serve as a refuge for species such as kelp bass, garibaldi, leopard sharks, and California spiny lobster, as well as a variety of marine invertebrates and bird species. Historically, Catalina Island has been inhabited by the Tongva people, and later developed as a recreational destination in the early 20th century. The marine area’s protection supports local commercial and recreational fishing by helping maintain healthy fish populations. Popular recreational activities include scuba diving and snorkeling in clear, kelp-filled waters, kayaking along rocky shorelines, and wildlife viewing of sea lions, dolphins, and migrating whales. The island's proximity to Los Angeles makes it a favorite destination for day trips and overnight visits focused on marine exploration and outdoor adventure. Visitors can access the area mainly through boat tours or private watercraft, with careful adherence to regulations designed to preserve the ecosystem. The MPA is co-managed by the California Department of Fish and Wildlife and local conservation organizations, enhancing community-based stewardship.
