HI! I am the lifeguard supervisor/dive team leader for Crystal Cove State Park. Crystal Cove is a designated "Underwater Park" and a Marine Life Refuge (Irvine Coast). Awesome variety of marine life and good diversity of bottom types. Excellent photography opportunities and limited recreational fishing (lobster and designated game fish only). Game hunters should expect to be checked every dive by park lifeguards, rangers, and game wardens. A new site of interest is a 150 year old historical anchor located just west of the Muddy Creek access ramp (east end of Reef Point parking lot) in approx 20 foot depth, about 150 yards off shore. Also, divers may now drop off / pick up gear at the entrance station to the Historic District (PCH / Crystal Cove signal light). This access provides for easy beach diving down and up coast of the beach cottages. Contact park lifeguards/rangers at 949 494-3539 for additional diving safety tips!
