Key Colony Beach

Key Colony Beach is a city in the middle Florida Keys, Monroe County, Florida, United States. The population was 788 at the 2000 census. As of 2004, the population recorded by the U.S. Census Bureau is 852.  Most of the city is located on an island formerly known as Shelter Key ; a small part of the city is on Fat Deer Key where the Sadowski Causeway (also 131st St Ocean on the Marathon, Florida street grid), which is the only road entering the city, connects to U.S. 1 (the Overseas Highway).

Key Colony Beach is reached over the Sadowski Causeway, which connects Key Colony Beach to Marathon, Florida on the east side of the city. It lies directly south of the City of Marathon, spanning a narrow cut.

Along the causeway are some charter fishing boats and a dockside restaurant called Sparky's Landing. At the base of the causeway, West Ocean Drive branches off first to the right and East Ocean Drive soon after branches to the left. On West Ocean Drive is the police station, along with the post office and town hall. In the same vicinity is a small park with a fountain and a gazebo. The entire ocean-facing side of West Ocean Drive is lined by various condominium complexes, while the side facing Marathon houses the Key Colony Inn and a small par-3 golf course. Starting at the far end of East Ocean Drive, streets are numbered one to fifteen east to west, and run from south to north toward Shelter Bay. The most notable buildings along East Ocean Drive are the Key Colony Beach Motel and the Key Colony Beach Club. At the tip of West Ocean Drive is Sunset Park, the place closest to where a woman was fatally struck by a spotted eagle ray. Many news reports were recorded from this park overlooking the very fertile shallows of where the Vaca Cut meets the Atlantic Ocean.
