Marathon's fishing heritage, old-Keys lifestyle and seafaring traditions are themes celebrated in the area's accommodations, such as private waterfront vacation homes, small hotels, beachside inns and tropical, family-style resorts. The area is popular for its annual seafood festivals and waterside restaurants that harvest and serve fresh fish, lobster and stone crab claws from local waters.

A federally protected section of the United States' only living coral barrier reef lies just a few miles offshore, at teeming formations such as Delta Shoals, Coffin Patch and Sombrero Reef, shallow sites popular for students learning to scuba dive.

In the deeper blue waters of the Florida Straits lie artificial reefs and the purposely-sunk wreck of the Thunderbolt.

On the north side of the island lie the calm waters of the Gulf of Mexico, Florida Bay and the Keys backcountry.
