BATTLE BIG-GAME FISH

Offshore Fishing in Key West

What is Offshore Fishing?

Offshore fishing—sometimes called deep sea fishing—is all about heading way out into the open ocean, usually 10 miles or more from land. In Key West, that means cruising into the deep waters of the Atlantic Ocean or the Gulf of Mexico. This is where the big fish live—like mahi-mahi, tuna, sailfish, and even the mighty marlin.

These trips are perfect for anglers who are ready for a real adventure. You’ll be using techniques like high-speed trolling, live bait fishing, or deep dropping to hook into powerful, hard-fighting fish. Offshore fishing in Key West isn’t just about the catch—it’s about the full experience: wide open water, salty breeze, and the thrill of never knowing what might hit your line next.

If you're looking for a full-day fishing challenge and a shot at some serious bragging rights, offshore trips are the way to go.
