Why dive here
Prince Island is a dive in California, United States. Water ranges 14-21°C, warmest July, August, September.
Prince Island, off the coast of California, offers divers a classic temperate water experience. We’ve found the kelp forests here are particularly lush, providing shelter for Garibaldi, sheepshead, and a variety of rockfish. Currents can sometimes be a factor, so it’s best for divers comfortable with moderate drift. It’s a solid pick for those looking to explore California’s signature underwater landscape.
