City Information

The Florida Keys is an archipelago or cluster of islands in the extreme southeast of the United States. The Keys extend from the southeastern Florida peninsula near Miami, run south and then curve west to Key West, and out to the uninhabited Dry Tortugas. The islands lie in the Florida Straits, dividing the Atlantic Ocean to the east from the Gulf of Mexico to the west, and creating Florida Bay. At the nearest point, the southern tip of Key West is just 90 miles (145 km) from Cuba.

Key Biscayne is actually attached at the north end to the mainland, and is therefore not considered part of the Keys by some Floridians. It is, however, part of the same geological formation, atop which sits coral rock islands, as well as partly-submerged mangrove islands. The city of Key West is the county seat of Monroe County, which covers mostly the Everglades on the mainland, and all of the islands from Key Largo south and west.
