The island's greatest treasure was underwater all along. Off Key Largo runs the Florida Reef — the only living coral barrier reef in the continental United States and among the largest reef systems on Earth. In 1960, after years of alarm at coral looting, the state created John Pennekamp Coral Reef State Park — the first undersea park in the United States, named for the Miami editor who fought for it. Since 1965 the park's emblem has been the bronze Christ of the Abyss, standing in twenty-five feet of water off Key Largo Dry Rocks with arms raised toward the surface light.
The park made the island the Diving Capital of the World. Dive shops line the highway; glass-bottom boats, snorkeling tours, and charters work Molasses Reef and the wrecks; and at Jules' Undersea Lodge, guests scuba down to the world's first underwater hotel and sleep beneath the surface. Coral nurseries now work to restore what heat and time have stressed — the island that once mined its reef now replants it.
Why People Visit Key Largo Florida
Key Largo is the Diving Capital of the World and the first of the Keys: the gateway island where the Overseas Highway begins, home of the first undersea park in the United States, the Christ of the Abyss beneath the reef, and the only living coral barrier reef in the continental U.S. — with the Everglades across the bay and Key West waiting down the road.
