The first undersea park in the U.S., John Pennekamp Coral Reef State Park encompasses approximately 70 nautical square miles. While the mangrove swamps and tropical hammocks in the park's upland areas offer visitors a unique experience, it is the coral reefs and their associated marine life that bring most visitors to the park. Many enjoy the view of the reef from a glass-bottom boat tour, but visitors can get a 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 enjoy walking on short trails, picnicking, or swimming at the beach. The Visitor Center has a 30,000-gallon saltwater aquarium and nature videos are shown in its theater.
