BEST SNORKELING SPOTBiscayne National Park9700 SW 328th Street
305-230-1144 Perennial winner and favorite of locals who want to avoid the famously crowded place next door, Biscayne National Park isn't the easiest spot to get to -- unless you have your own watercraft. Fortunately the concessionaire has a wide range of tours, boat and equipment rentals, and trips, including jaunts to the mere five percent of the park that sits above the high-tide line. (Yes, this park is almost completely submarine.) Especially intrepid divers should consider visiting the archaeological wrecks on the eastern flank. Reservations are highly recommended because access to the park is limited, a fact that contributes to its continued vitality.
