About this site
Santa Catalina Island sits off the coast of Southern California, across the channel from the Los Angeles area, and Harbor Reef lies along one of the nearshore rocky stretches typical of the island's kelp-lined coast, reached by boat from towns like Avalon and Two Harbors. It is a beginner dive to around 15 metres. Divers have reported leopard sharks and moray eels here, along with the kelp-forest life typical of the area.
