Established in 1963, John Pennekamp Coral Reef State Park was the first undersea park created in the United States. The park, combined with the adjacent Florida Keys National Marine Sanctuary, encompasses 178 nautical square miles of coral reefs, seagrass beds and mangrove swamps. These areas were established to protect and preserve the only living coral reef in the continental United States.

Named for the late Miami newspaper editor John D. Pennekamp, who was also instrumental in preserving the land that would become the Everglades National Park, Coral Reef State Park now enjoys over a million visitors per year from around the world

Visitor Center and Aquarium

The Visitor Center features a 30, 000 gallon saltwater aquarium and other natural history exhibits interpreting the park’s unique marine environment. There is also a theater where visitors may watch nature videos. Hours are from 8am to 5pm daily.

Environmental Education

At Pennekamp Park, visitors can learn about the reef, reef animals, snorkeling, diving, and much, much more. Throughout the year, there are many environmental programs offered to park visitors on a wide range of natural and cultural history subjects. Guided nature walks along the Mangrove and Wild Tamarind trails are offered seasonally or upon request by individuals and organized groups.
