Boot Key Harbor
Boot Key Harbor can be accessed by boat via two inlets from the Atlantic Ocean. The western inlet has a controlling depth of 6 feet at mean low-tide, as does the rest of the main channel within the harbor. Sister Creek provides access from the south and has a low-point of 4.2 feet at mean-low tide.
Boot Key Harbor is well protected from severe sea conditions and is popular with recreational boaters seeking refuge from storms. A large portion of Boot Key Harbor is occupied by a 226-buoy municipal mooring field administered by the City of Marathon, Florida, United States.
Boot Key Bridge spans the west end of Boot Key Harbor connecting Key Vaca with Boot Key to the South. The bridge is currently closed to pedestrian and vehicular traffic, and the bascule section was removed on October 26, 2010.
