Key West sits at the end of the Florida Keys chain with access to both Atlantic and Gulf waters. The backcountry flats hold tarpon, bonefish, and permit — the Grand Slam of fly fishing — while offshore waters produce sailfish, marlin, and mahi-mahi year-round.
Key West occupies a unique position at the southern tip of Florida where the Gulf of Mexico, Atlantic Ocean, and Florida Straits converge. This creates access to deep Gulf Stream waters, expansive backcountry flats, and world-class reef systems — all within minutes of the harbor.
The deep blue water close to shore supports sailfish, mahi-mahi, and yellowfin tuna, while the surrounding flats are home to tarpon, permit, and bonefish — some of the most prized species in light-tackle fishing.
Few destinations offer this range of fishing environments in such close proximity, which is why Key West consistently ranks among the top charter fishing destinations in the world.
When is tarpon season in Key West?
