The Florida Keys are known around the world for their stunning beauty and unbeatable fishing. But if you’re specifically looking to try flats fishing, you may be wondering—which Key is the best? The answer, hands down, is Islamorada. Nicknamed the “Sportfishing Capital of the World,” Islamorada offers access to crystal-clear flats, an incredible mix of game fish, and seasoned guides ready to show you the ropes.
In this blog, we’ll explain why Islamorada tops the list, what kind of fish you’ll find in the flats, the best times to visit, and how you can start your own flats fishing adventure.
Islamorada sits in the Upper Keys, between Key Largo and Marathon. This strategic location gives anglers access to both the Atlantic Ocean and Florida Bay. But what really makes Islamorada shine is the quality of its flats—shallow, calm, and loaded with fish.
Here, the flats are typically no more than 1 to 6 feet deep, which is perfect for sight fishing and fly casting. You can see the fish before you cast, making the experience exciting and visual. Whether you’re casting from a flat boat, wading, or even trying from a kayak, Islamorada offers some of the best conditions for this style of fishing.
Flats fishing isn’t just relaxing—it’s also your chance to catch some of the most sought-after fish in Florida. The three most famous species are:
Bonefish are fast, smart, and thrilling to catch. They’re often found in shallow sand and grassy areas. Most range between 3–5 pounds, though some reach double digits. They’re especially active from March through October.
These giants, also known as “Silver Kings,” can weigh over 100 pounds. They leap into the air when hooked and put up an unforgettable fight. Tarpon are best targeted from mid-March to mid-July, though some stick around all year.
Permits are tricky. They spook easily and are known for their keen senses. You’ll find them in the same areas as bonefish, especially from late February through April, and again in the clear summer months.
Catch all three in one day and you’ll have pulled off the Florida Keys Inshore Grand Slam—a real badge of honor for anglers.
Beyond the “Big Three,” Islamorada flats also hold:
Barracuda – Best in winter months; aggressive and fast.
Jack Crevalle – Present year-round and always ready to strike.
Redfish – Often seen in grassy shallows.
Spotted Seatrout – Active in cooler months.
Mangrove Snapper – Found from fall through early spring.
Sharks – Small inshore species like bonnetheads and lemons are common from December to March.
Islamorada is fishable year-round, but each season offers something different:
Spring (March–May): Peak time for tarpon and permit.
Summer (June–August): Great visibility and strong action for bonefish and permit.
Fall (September–November): Still good for bonefish, with fewer crowds.
Winter (December–February): Excellent for barracuda, snapper, redfish, and seatrout.
Hiring a local captain is your best bet. These shallow boats are built to move quietly through the water. Guides know the local hot spots and conditions. They also provide gear, bait, and fishing licenses, so you can focus on the experience.
This is a peaceful and stealthy way to explore the flats. You’ll need good paddling skills and some stamina, but it’s a rewarding challenge. Kayaks let you sneak up close to fish that might flee from a boat.
Islamorada’s flats are part of a protected marine zone. That means certain species, like bonefish and tarpon, are catch-and-release only. For others, strict bag limits apply. If you’re not fishing with a licensed guide, you’ll need a Florida fishing license if you’re 16 or older.
Also, be prepared for the sun. Wear light, long-sleeved shirts, sunscreen, and a hat. Polarized sunglasses are a must for spotting fish in the water.

Islamorada is often called the “Sportfishing Capital of the World.” Located in the Upper Keys, it offers phenomenal offshore, reef, and flats fishing year-round. Anglers target everything from Tarpon and Bonefish to Sailfish, making it a top destination.
In the Florida Keys flats, popular fish include Bonefish, Permit, and Tarpon. Other frequent visitors are Barracuda, Jack Crevalle, Redfish, Spotted Seatrout, and Mangrove Snapper. These species thrive in the clear, shallow waters that make flats fishing so rewarding.
Flats are found all along the Florida Keys, from Key Largo to Key West. Prime areas include Islamorada, Biscayne Bay, Marathon, Big Pine Key, and the Marquesas. These shallow, sandy-bottom zones are ideal for sight casting and targeting inshore game fish.
