I've got an idea to dive Catalina and then shore dive the Laguna Beach area this summer. I'm familiar with Dana Point and will ferry to Catalina from there. I'll dive at Casino and I'm pretty okay with the logistics there since it's a return trip. But could you all give me your thoughts about Laguna, particularly Treasure Island and Shaw's Cove. Are these doable for a relatively inexperienced diver (assuming no high surf) with a guide? I planned to snorkel Shaws's one day, but the surf was HUGE! Any local shops or dive clubs I should contact? Any of you interested? Any predictors for good clarity...low/high tide, weather, moon phases, etc? I have a 5 mm wet suit with a 5/3 hooded vest. What do I need to know before making plans? Thanks!
