The John Pennekamp Coral Reef State Park is the first undersea park in the United States. It was established in 1963 to protect and preserve the only living coral reef in the nation. Connected with the Florida Keys National Marine Sanctuary, together they span more than 178 nautical square miles, which include coral reefs, mangrove swamps, and sea grass beds. With so many underwater experiences to discover, guests are encouraged to kayak, snorkel, and dive independently or to join one of the snorkel, scuba, and glass bottom boat tours. The park Visitor Center also has a 30,000 gallon saltwater aquarium and a theater showing nature films.
