Adventure Fishing in the Florida Keys

With its unique island location, Marathon anglers enjoy spectacular fishing in the Florida Keys 12 months a year. The Gulf of Mexico abounds with snapper and grouper while backcountry flats teem with bonefish, tarpon and permit. Oceanside is an outer reef that is a magnet for a wide variety of fish species. Some of the world's best sport fishing waits just outside the reef, where you'll find dolphin, tuna, marlin and sailfish. The Adventure Fishing Director at our resort would be pleased to help you plan the perfect Marathon fishing trip. More about Adventure Fishing
