I will be in area (1st time) for weekend with friend (staying Dana Pt Ritz) end of June. We are both certified divers, would like a nice area to snorkel while there -- I see couple people mention Laguna Beach, and specifically Shaw's Cove and Crescent Bay area -- can anyone give us any specifics on these areas? pros/cons or any other recommended area nearby?? hear the ocean can be cold -- should we pack our wetsuits?? ANY insight appreciated!
