Long Key is an island in the middle Florida Keys. U.S. 1 (or the Overseas Highway) crosses the key at approximately mile markers 65.5--71, between Fiesta Key and Conch Key. It is the home of Long Key State Park, a favorite of campers and nature lovers despite the lack of a beach and the proximity of noisy U.S. 1. It is smaller and less developed than the neighboring incorporated village of Islamorada to the northeast and city of Marathon to the southwest. The city of Layton is located on Long Key.
