The Florida Keys are a coral cay archipelago extending ~120 miles (190 km) from Key Largo to Key West off Florida's southern coast. Divided into Upper Keys (nearer mainland) and Lower Keys (farther offshore), they are connected by the Overseas Highway (US 1), one of America's most scenic drives.
Key West, the southernmost point in the continental U.S., hosts the famous Southernmost Point Buoy landmark. The Keys offer world-class snorkeling, diving, fishing, and historic sites like the Ernest Hemingway Home.
