Biscayne National Park's Maritime Heritage Trail offers an exciting opportunity to explore the remains of some of the park's many shipwrecks. Six wrecks, spanning nearly a century and a wide variety of sizes and vessel types, have been mapped, brochures have been produced and mooring buoys have been installed. The newest addition to the trail is the Fowey Rocks Lighthouse. Snorkeling is great around the base of the light, but the structure itself is not open to the public.
