John Pennekamp Coral Reef State Park

Opened in 1963, John Pennekamp Coral Reef State Park is America's first undersea park—and remains a sight to behold. Within its 70 nautical miles, visitors can explore a vast collection of gorgeous coral reefs, mangrove swamps, and seagrass beds via kayak, canoe, paddleboard, or glass-bottomed boat. There are also opportunities for scuba diving and snorkeling, which give guests an up-close view of the more than 250 species of tropical fish that call this vast park home.
