Marathon sits in the heart of the Florida Keys, making it the perfect base for accessing both the Atlantic flats and the Gulf side shallows. The oceanside features dramatic coral reefs teeming with mutton snapper, yellowtail snapper, and grouper. The Gulf side backcountry offers hundreds of square miles of grass flats and mangrove channels holding bonefish, permit, and tarpon.
The Seven Mile Bridge area produces outstanding fishing for a wide range of species. Anglers jigging near the bridge pilings catch permit, cobia, and amberjack. At night, the bridge lights attract ballyhoo and other baitfish that draw large snook and tarpon. The nearby patch reefs are exceptional for snorkeling and spearfishing.
Offshore fishing from Marathon reaches the Hump — a famous deep-water seamount that concentrates blue marlin, tuna, and sailfish. The nutrient-rich waters around the Hump make it one of the most productive offshore spots in the Keys. Check the wind and wave forecasts above before making an offshore run to the Hump or Dry Tortugas.
