Best Deep Sea Fishing Fishing Spots in Key Largo
Top spots where local captains target blackfin tuna and other deep sea fishing species.
Gulf Stream (Key Largo)
The Gulf Stream passes within 5-8 miles of Key Largo's reef line, bringing warm bluewater and pelagic species remarkably close to shore. Sailfish, mahi-mahi, wahoo, and blackfin tuna patrol the current edges and weed lines. Key Largo's proximity to the Stream makes it one of the most accessible bluewater fisheries in Florida, with boats reaching productive water in under 30 minutes.
The Wall (Key Largo)
The Wall refers to the dramatic reef drop-off where the shallow reef shelf plunges from 100 feet to over 600 feet along the eastern edge of the Florida Straits. Swordfish, tuna, and wahoo patrol the depth transition, while deep-dropping produces tilefish, queen snapper, and snowy grouper. The Wall is accessible on half-day trips from Key Largo due to its close proximity.
USCG Duane Wreck
The USCG Duane is a 327-foot Coast Guard cutter sunk in 1987 as an artificial reef approximately 1 mile south of Molasses Reef in 120 feet of water. The wreck holds massive goliath grouper, amberjack, barracuda, and schools of horse-eye jacks. It is one of the most iconic wreck dives and fishing sites in the Florida Keys.
USCG Bibb Wreck
The USCG Bibb is a 327-foot Coast Guard cutter resting upright in 130 feet of water near the Duane, approximately 7 miles offshore of Key Largo. The wreck attracts amberjack, almaco jacks, barracuda, and large grouper that hold in and around the hull structure. Deep-jigging and dropping baits alongside the wreck produces trophy-class fish on full-day charters.
