Corona Del Mar would be a nice dive site for beginner scuba. I dove left of the channel near the jetty, under the boat moorings. Did see some nice sheep crab and a few Calico bass, but not much else. Lots of sand; it reminded me of Monterey State Beach. Parking $8.00 at the gate for all day, or you can park up on the hill, but it's a long way down to beach.
