Florida: Florida Keys – John Pennekamp State Park
Established in 1963, John Pennekamp Coral Reef State Park was the first undersea park in the United States. John Pennekamp Coral Reef State Park, and the adjacent Florida Keys National Marine Sanctuary, cover approximately 178 nautical square miles of coral reefs, seagrass beds and mangrove swamps. We had the chance to spend a couple of days exploring this wonderful place in winter (a good time to go!)
