About this site
Catalina Island sits in the Pacific off the coast of Southern California, about 22 miles from the mainland near Los Angeles and Long Beach. The island's waters are part of the California Channel Islands chain and are reached mostly by boat from Avalon or Two Harbors, with kelp forests lining much of its rocky shoreline. Diving here is generally rated as beginner level, making it an accessible spot for those getting used to the cooler Pacific waters and kelp environment.
