The Florida Keys sit between the Atlantic Ocean and the Gulf of Mexico, with the only living coral barrier reef in the continental U.S. running along the Atlantic side and thousands of acres of shallow flats, mangrove islands, and tidal channels spread across the backcountry to the west. That geography creates three very different fishing environments, all within a short drive of each other.
Each style of fishing in the Keys offers a different experience, targets different species, and suits a different kind of angler. Here is what to expect from each one.
Deep-Sea Fishing
Deep-sea fishing in the Keys means heading offshore past the reef line and into open Atlantic or Gulf waters. Depending on the charter and the target species, that could mean running five miles out to the reef edge or 20 or more miles offshore to deeper structure.
What you are fishing for
-
Mahi-mahi, yellowfin and blackfin tuna, wahoo, sailfish, kingfish, and marlin offshore
-
Grouper, snapper, amberjack, and cobia over reefs and wrecks closer to shore
-
Mahi-mahi are most abundant spring through summer, sailfish peak November through March, and grouper season generally runs May through December
How it works
-
Most offshore charters use trolling, dragging lines behind the boat at a steady speed to cover water and locate fish
-
Bottom fishing over reefs and wrecks is common on half-day trips that stay closer to shore
-
The captain and mate handle the rigging, bait, and fish-finding; your job is to hold the rod when something bites
Who it is for
-
Beginners and experienced anglers alike; the crew does the technical work
-
If you have never fished before, the captain will walk you through everything
-
If you are experienced and want to target a specific species, a good captain will adjust the plan
What to know
-
The ride offshore can be rough depending on conditions; take seasickness medication before departure if needed
-
Trips are typically four, six, or eight hours; longer trips allow the captain to run farther and fish more water
Backcountry Skiff Fishing
Backcountry fishing is the opposite of offshore in almost every way. Instead of deep blue water and big swells, you are fishing in a few feet of water across the flats and mangrove channels that stretch between the Keys and the Everglades. The water is calm, clear, and protected.
What you are fishing for
-
Tarpon, bonefish, permit, redfish, snook, spotted seatrout, barracuda, and sharks
-
The Keys Grand Slam means landing a tarpon, a bonefish, and a permit in the same day
-
Tarpon peak from mid-March through July and can reach well over 100 pounds; permit fishing is best late February through April and again in June and July; winter months bring strong action on redfish, trout, barracuda, and sharks
How it works
-
Guides use shallow-draft skiffs, typically 16 to 20 feet long, that can float in as little as 10 to 12 inches of water
-
The guide stands on a raised platform at the stern and uses a push pole to move the boat silently across the flats
-
This is sight fishing: you watch for fish, spot them, and make a precise cast; a good guide will coach you through it
Who it is for
-
Anglers who enjoy the hunt as much as the catch; more technical than offshore, but the individual moments are intense
-
A good option for families with younger kids who might get uncomfortable on rougher offshore seas
-
Many guides will adjust toward easier species like snapper, jacks, and seatrout when fishing with beginners or children
What to know
-
Most flats skiffs accommodate one or two anglers, sometimes three if fishing the deeper channels
-
Bring polarized sunglasses in amber or brown tints to help spot fish through the surface glare
-
Bug spray is worth having, especially in summer when mosquitoes can be thick in the mangroves
Bridge and Pier Fishing
The Florida Keys have 42 bridges connecting the islands along the Overseas Highway, and many of them double as fishing platforms. Bridge fishing is free, accessible, and surprisingly productive. You do not need a boat or a guide. Just a rod, some bait, and a spot along the railing.
What you are fishing for
-
Mangrove snapper, yellowtail snapper, grouper, barracuda, mackerel, tarpon, permit, and sharks
-
The bridges create structure underwater with old pilings, construction debris, and rock walls that attract baitfish, which in turn attract everything else
-
The bigger bridges like the Seven Mile Bridge near Marathon and the Bahia Honda Bridge offer the most variety
How it works
-
Most bridge anglers use live shrimp, cut bait, or small jigs dropped near the pilings and in the shadows under the bridge
-
Tides play a major role; moving water, especially during a tide change, tends to produce the best action
-
Many experienced bridge anglers fish at night, when snapper and tarpon feed more aggressively around the lit pilings; a chum bag helps draw fish closer
Who it is for
-
Anyone; a great entry point for first-time anglers and a serious pursuit for experienced fishermen who know how to work the structure and the tides
-
Free to fish (you will need a Florida saltwater fishing license unless you are on a pier that covers it)
-
Works for 30 minutes or all night
What to know
-
Use heavier line than you might expect; fish near the pilings will try to wrap you around the structure, and lighter line gets cut quickly
-
Arrive early on weekends at popular spots like Channel 2 and Channel 5 in Islamorada, as the best positions fill up
-
Parking is available at most bridge access points but can be limited
