Best Deep Sea Fishing Fishing Spots in Marathon
Top spots where local captains target swordfish and other deep sea fishing species.
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.
