About Deep Sea Fishing Fishing in Marathon
Marathon, Florida offers some of the finest deep sea fishing fishing on the Gulf Coast. Marathon sits in the heart of the Florida Keys with unique access to both Atlantic and Gulf of Mexico waters, making it one of the most versatile fishing destinations in the island chain. The legendary Seven Mile Bridge creates a massive artificial reef that attracts tarpon, permit, barracuda, and snapper, while the surrounding flats and channels hold bonefish, redfish, and snook. The Atlantic reef line is loaded with yellowtail snapper, mutton snapper, grouper, and hogfish, and the offshore humps and wrecks produce mahi mahi, wahoo, blackfin tuna, and sailfish. Marathon's central Keys location means shorter runs to productive fishing grounds in every direction. The area's family-friendly atmosphere, dolphin research center, and access to incredible fishing make it an ideal Keys destination for anglers of all ages. The deep sea fishing waters here — deep Gulf waters beyond the continental shelf, blue water, and offshore reefs — provide world-class angling opportunities that draw fishermen from across the country.
Deep Sea Fishing anglers in Marathon target an impressive roster of species including Blackfin Tuna, Sailfish, Swordfish, Wahoo, Yellowfin Tuna and more. Peak season runs through January, February, December, but productive deep sea fishing fishing is available year-round.

Best Deep Sea Fishing Fishing Spots in Marathon
From legendary bays to productive reefs, here are the top deep sea fishing fishing spots your captain will target in the Marathon area.
Marathon Hump (Middle Hump)
The Marathon Hump is a prominent deepwater seamount south of Marathon where the ocean floor rises dramatically from 1,100 feet to around 480 feet. This structure concentrates blackfin tuna, yellowfin tuna, wahoo, and mahi-mahi, and is one of the most productive deep-dropping spots for swordfish in the Middle Keys. The Hump is a bucket-list destination for serious offshore anglers.
Gulf Stream (Marathon)
The Gulf Stream flows approximately 10-15 miles south of Marathon's reef line, bringing warm bluewater current and pelagic species within range. Sailfish, mahi-mahi, wahoo, and blackfin tuna patrol the Stream edges, especially along weed lines and color changes. Marathon's central Keys location provides access to productive Gulf Stream fishing grounds.
West Hump (from Marathon)
The West Hump is another deepwater seamount accessible from Marathon, lying roughly 20 miles southwest. The bottom rises from deep water to create a fish-concentrating feature that holds swordfish, tuna, wahoo, and mahi-mahi. Marathon boats can fish both the Marathon Hump and West Hump on a single offshore trip when conditions allow.
Marathon Deep Wrecks
Several deep wrecks lie in 200-plus feet of water south of Marathon along the outer edge of the reef system. These sunken vessels hold large amberjack, almaco jack, barracuda, and grouper on the structure, while pelagics cruise overhead in the current. Deep wreck fishing is a productive alternative to humps when targeting bottom species offshore.
