The comment about this park not allowing snorkeling is false. I snorkeled with a buddy four times here in July and August of 2009. This may be a great scuba site but it is not a great snorkeling site. Within the cove the water was often murky and the sea life was close to non existent. Outside the cove the visibility opens up but the depth keeps things of interest out of sight for snorkelers. This is the only dive sight I visited in California and it did not live up to the hype I heard about when asking for a good snorkel site. Maybe I am just spoiled from all my Caribbean diving.
