If you're wanting to stay away from large crowds and feel somewhat secluded, Larsen's Beach is the place to be. While you will have to hike a small trail to get to the beach, the path is usually easily navigable. Be sure to note the location of channels entering the ocean as you make your way down; the currents near these channels are often swift and should be avoided. In light of this, swimming is not a good idea at Larsen's (the water is also too shallow). However, there is some excellent snorkeling at Larsen's, but be sure not to extend yourself into portions of the reef where you cannot easily stand up at-will.
