Property description

This rare 9-acre waterfront parcel is located on secluded Boot Key, a largely undeveloped island within the city limits of Marathon in the heart of the Florida Keys. Accessible only by boat since the drawbridge connection to Vaca Key was removed in 2010, the property offers privacy, natural beauty, and exceptional potential. Zoned mixed use, it includes 24 existing docks, a building and radio towers from a former local radio station, and portions of the land currently leased to fishermen. There are no active utilities on site, making it a true blank canvas for future development or a private retreat. With motivated ownership and flexible possibilities, this is a unique opportunity to secure a piece of the Florida Keys.
