Adventure Fishing in the Florida Keys

Marathon anglers enjoy spectacular fishing in the Florida Keys 12 months a year. The Gulf of Mexico abounds with snapper and grouper, while the 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, with dolphin, tuna, marlin and sailfish inhabiting the waters.
