John Pennekamp Coral Reef State Park is located at Mile Marker 102.5, north of Key Largo in the Florida Keys. 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. The park extends 3 miles into the Atlantic Ocean and is approximately 25 miles in length. These areas were established to protect and preserve a portion of the only living coral reef in the continental United States. The park is named for the late John D. Pennekamp, a Miami newspaper editor, whose efforts contributed to the establishment of Everglades National Park and the preservation of what would become John Pennekamp Coral Reef State Park.
