Welcome to John Pennekamp Coral Reef State Park
Key Largo’s John Pennekamp Coral Reef State Park is one of a kind, offering an amazing glimpse into the underwater world.
Renowned for being the country’s first undersea park, John Pennekamp Coral Reef State Park encompasses an impressive 70 nautical square miles. While many visitors view the park’s colorful coral reefs and teeming marine life on a glass-bottom boat tour, one can get an even closer look by scuba diving or snorkeling. Canoeing and kayaking through the park's waters are popular activities; fishing is permitted in designated areas.
Visitors can also enjoy walking on short trails through tropical hammocks, picnicking or swimming at the beach. The visitor center features several large saltwater aquariums filled with sea creatures, and nature videos are shown in its theater. Full-facility and youth/group campsites are available.
