See the only living coral barrier reef in the continental United States on this two-hour glass-bottom boat tour from Key West! As you relax on the cruise, look down below your feet to see the reef, which is teeming with tropical fish, hard and soft corals, sponges, snails, jellyfish, anemones, crabs, lobsters, rays, sea turtles, nurse sharks and other sea life. Upgrade to the sunset cruise to enjoy Champagne and soft drinks as you watch the sunset.
