About Inshore Fishing in Marathon
Marathon, Florida offers some of the finest inshore 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 inshore waters here — calm bays, estuaries, grass flats, and mangrove-lined shorelines — provide world-class angling opportunities that draw fishermen from across the country.
Inshore anglers in Marathon target an impressive roster of species including Flounder, Mangrove Snapper, Pompano, Redfish, Sheepshead and more. Peak season runs through April, March, May, but productive inshore fishing is available year-round.

Best Inshore Fishing Spots in Marathon
From legendary bays to productive reefs, here are the top inshore fishing spots your captain will target in the Marathon area.
Seven Mile Bridge
The historic Seven Mile Bridge connects Marathon to the Lower Keys and is one of the most famous fishing bridges in the world. Tarpon, permit, barracuda, and mangrove snapper congregate around the old bridge pilings during tidal changes. The bridge channel is a major tarpon migration corridor from April through July, with fish exceeding 100 pounds.
Boot Key Harbor
Boot Key Harbor is a large, protected harbor on the south side of Marathon offering sheltered inshore fishing for snook, mangrove snapper, yellowtail snapper, and tarpon. The harbor's docks, channel markers, and mooring balls provide structure that concentrates gamefish. Night fishing under the harbor lights produces consistent snapper and tarpon action.
Vaca Cut
Vaca Cut is a deep channel between Vaca Key and Fat Deer Key in the heart of Marathon, funneling strong tidal currents that attract tarpon, snook, and barracuda. The cut is narrow enough to cast across during outgoing tides when bait gets swept through the channel. Mangrove snapper and yellowtail snapper hold along the bridge pilings year-round.
Marathon Bayside Flats
The shallow flats on the Gulf side of Marathon stretch across expansive turtle grass beds toward the Content Keys and Nine Mile Bank. Permit, bonefish, and barracuda cruise the flats in skinny water, with guides poling skiffs for sight-fishing on calm mornings. The flats are less pressured than the Islamorada backcountry and offer excellent year-round fishing.
