15th Street Marina Marathon (at Boot Key Harbor)

4.9 (11 reviews)

Tucked on the ocean side of Marathon just south of Boot Key Harbor, 15th Street Marina offers around 25–28 wet slips accommodating yachts and sailboats, plus commercial dockage. The location puts you right on the Florida Keys waterfront, with easy access to the Atlantic and the sheltered anchorage of Boot Key Harbor nearby. Marathon's dining, dive shops, and the Seven Mile Bridge are all a short ride away.
