Boot Key is an island in the middle Florida Keys located adjacent to Key Vaca. Boot Key is within the city limits of Marathon, Florida, United States. The island is largely undeveloped. A draw bridge that once connected the island to Key Vaca was demolished by the city in 2010 after failing FDOT's inspection. "Boot Key has been protected from development since 2011 by NOAA’s Coastal & Estuarine Land Conservation Program." Immediately adjacent to Boot Key is a 38 acre tract of land from which the United States Government broadcasts Radio Marti. These broadcasts consist of anti-communist news and information directed towards residents of Cuba, in an attempt to support opposition against the Cuban government. A hawk watch is conducted every fall on Boot Key.
