The Florida Keys Sights

Getting lost in the Keys is almost impossible once you understand the unique address system. Many addresses are simply given as a mile marker (MM) number. The markers are small, green, rectangular signs along the side of the Overseas Highway (U.S. 1). They begin with MM 126, 1 mi south of Florida City, and end with MM 0, in Key West. Keys residents use the abbreviation BS for the bay side of U.S. 1 and OS for the ocean side. From Marathon to Key West, residents may refer to the bay side as the gulf side.

The Florida Keys are divided into four areas: the Upper Keys, from Key Largo to the Long Key Channel (MM 106-65) and Ocean Reef and North Key Largo, off Card Sound Road and Route 905, respectively; the Middle Keys, from Conch (pronounced konk) Key through Marathon to the south side of the Seven Mile Bridge, including Pigeon Key (MM 65-40); the Lower Keys, from Little Duck Key south through Big Coppitt Key (MM 40-9); and Key West, from Stock Island through Key West (MM 9-0).
