Can anybody please give me exact instructions ( economically turn-by-turn ) how to get to the "famous La Jolla Caves", that's what I've been practically hearing is the best snorkeling site in the area. In some manner i've been to La Jolla Cove before, are they far from the Cove? Is it realy a good snorkeling out there? Do I need a wetsuit at this time of year? How cold is the water?
