Islamorada sits in the Upper Florida Keys, a string of islands between the Atlantic Ocean and Florida Bay. The town has called itself the Sportfishing Capital of the World since the 1940s, and while plenty of fishing towns throw around big claims, this one has the history and the water to back it up.
This is where backcountry flats guiding was essentially invented. The guides who poled the first skiffs across the Florida Bay flats, sight-casting to tailing bonefish and rolling tarpon, were working out of Islamorada. Bud N' Mary's Marina has been running fishing charters from the same docks since 1944, it's the oldest and largest charter fleet in the Keys, and the institutional knowledge on those docks is measured in generations, not years.
What makes Islamorada special isn't just history, it's geography. The islands sit at the convergence of Florida Bay, the Gulf of Mexico, and the Atlantic Ocean. That means three distinct fisheries within a 20-minute boat ride: the backcountry flats, the oceanside reef, and the deep blue water of the Gulf Stream.
The Flats, Bonefish, Permit, and the Grand Slam
The flats fishery is what put Islamorada on the map. Stretching west from the islands into Florida Bay, thousands of acres of shallow turtle grass and white sand flats hold bonefish, permit, tarpon, and redfish.
Bonefish are the gateway drug. They cruise the flats in pods, tailing as they root for shrimp and crabs in the grass. A guide poles a shallow-draft skiff across the flat, spots the fish, and you get one cast, maybe two. A well-placed shrimp or crab pattern lands ahead of the pod, the lead fish tips down and eats, and your reel screams as 100 yards of line disappears in three seconds. Bonefish in Islamorada average three to seven pounds, with fish over eight pounds available for anglers who put in the time.
Permit are the prize. They're widely considered the most difficult fish to catch on fly or light tackle in shallow water, spooky, selective, and maddeningly unpredictable. Islamorada's oceanside flats, wrecks, and channel edges hold permit year-round, and the dedicated guides who specialize in them have developed an expertise that exists nowhere else. A permit on fly is a career fish for most anglers.
The Grand Slam, catching a bonefish, permit, and tarpon in a single day without returning to the dock, was born on these flats. It remains one of the rarest achievements in sportfishing. The geometry works here because all three species share overlapping habitat, and a guide who reads the tide and the conditions can move between bonefish flats, permit wrecks, and tarpon channels in a single session. It doesn't happen often, but when it does, it happens in Islamorada more than anywhere else.
The Backcountry, Snook, Redfish, and Tarpon
The backcountry is the maze of islands, mangrove creeks, and shallow basins that make up the western side of Florida Bay, stretching toward the Everglades. It's a different world from the open flats, darker water, tighter quarters, and fish that live in the structure.
Snook line every mangrove shoreline, holding in the roots and ambushing bait on the tide. Backcountry snook fishing is a close-quarters game, you're casting into pockets no bigger than a bathtub, and the fish has to eat before it realizes something is wrong. Live pilchards, white bucktail jigs, and topwater plugs at dawn are the standards.
Redfish work the shallow basins and mangrove edges, often in schools that push wakes across the surface. They're less technical than bonefish but just as rewarding on light tackle, a tailing red in a foot of water, copper back glowing in the sun, is one of the most beautiful sights in fishing.
Tarpon pour through the backcountry channels and basins from April through July. The channels between islands funnel tide-driven bait, and tarpon set up in the current to feed. Backcountry tarpon tend to be smaller than the oceanside fish, 30 to 80 pounds, but they're in tighter water, which makes the fights more intense and the visuals more dramatic. A rolling tarpon exploding on a bait in a mangrove creek six feet wide is an experience you don't get anywhere else.
Offshore, The Reef and the Blue Water
Islamorada's Atlantic side drops off the flats into the reef tract and then into the Gulf Stream. The reef sits in 15 to 80 feet of water and holds yellowtail snapper, mutton snapper, grouper, hogfish, and barracuda. It's excellent year-round fishing, productive on live bait and cut bait, and the trips are short, the reef is minutes from the dock.
Beyond the reef, the Gulf Stream runs within a few miles of Islamorada, carrying the deep-water pelagics. Sailfish peak in winter (November through March), mahi-mahi run spring through fall, wahoo show up in winter, and blackfin tuna school along the color changes year-round. The offshore charter fleet, head boats, sport fishers, and center consoles, runs daily out of Bud N' Mary's and the other Islamorada marinas.
Swordfish have become a growing fishery, deep-drop daytime swordfishing with electric reels has opened up a fishery that was previously only available at night. Islamorada boats are among the most experienced in the Keys at targeting swords.
When to Go
Islamorada fishes year-round, but the peaks by target species:
- January–March: Peak sailfish, permit on the wrecks, bonefish starting to show on the flats
- April–June: Tarpon, this is the main event, with fish stacked in channels and along the bridges
- July–September: Backcountry snook and redfish in the mangroves, mahi-mahi offshore, bonefish on the flats
- October–December: Permit season, sailfish starting, yellowtail snapper on the reef, cool-weather bonefish
