Marathon

Here, the bridges of The Florida Keys connect more than islands. Marathon brings visitors closer through family-friendly fun, wildlife encounters and vacation time well spent.

The Heart of the Keys, Made for Families

From Long Key to the Seven Mile Bridge (MM 47–61), Marathon offers easy access by land or sea. This stretch of The Keys is built for boaters, fishing, families and anyone who loves life on the water. Snorkel Sombrero Reef, explore the Turtle Hospital or meet dolphins up close. Stroll the Old Seven Mile Bridge or wander Crane Point’s trails through hardwood hammocks. Stay at laid-back inns, dockside rental homes or luxurious resorts. In Marathon, every day mixes nature, play and discovery, making it the ideal destination for visitors of all ages to reconnect and relax.
