Come Visit Us In Marathon,

“The Heart of the Florida Keys”

Boot Key Harbor is located in the heart of the Florida Keys, entirely LookingWestwithin the Marathon city limits. It is renowned for its combination of weather protection and relatively deep water. Just off-shore lies Sombrero Reef and the beautiful waters of the Florida Keys National Marine Sanctuary.

The City Marina administers a 226-ball mooring field that occupies most of Boot Key Harbor, in addition to a large anchorage area south of the main Harbor channel, between Sister Creek and the Boot Key Bridge.

Access to the Harbor is provided by two inlets from the Atlantic Ocean. The West entrance is generally considered the main entrance and has a controlling depth of 6’ MLW (mean low-water), as does the rest of the channel within the Harbor.

Come visit us by land –
We’re located at MM 49 on US1 “The Overseas Highway” and adjacent to the beautiful Marathon Community Park!
