Why dive here
Twin Rocks is a pinnacle dive in California, United States. Water ranges 14-21°C, warmest July, August, September.
Twin Rocks offers a straightforward shore dive, popular with local divers looking to log some bottom time. We usually find kelp clinging to the rocky reef, home to typical California critters like Garibaldi and various rockfish. It's a solid choice for a casual afternoon dive, especially for those new to temperate water diving or just looking to practice skills. Expect decent visibility on calm days.
