Boot Key, Marathon, Florida Keys

Situated beside the city of Marathon, Boot Key is a quiet, mostly undeveloped island in the Middle Florida Keys. It is best experienced from the water, with mangrove-lined shores, shallow flats, and a more secluded feel than many nearby destinations. A bridge once linked the island to Marathon, but Boot Key is now generally reached by kayak, paddleboard, or private boat, helping preserve its rustic character.
For many visitors, the appeal of Boot Key is not a built attraction but the chance to enjoy a peaceful stretch of Keys shoreline close to town. Nearby Marathon provides launches, marinas, outfitters, dining, and other services, while the island itself remains a low-key nature spot.
