The upper Keys' crown jewel — world-class reef snorkeling, legendary backcountry flats fishing, coral diving, and boat rentals on the turquoise waters between the Atlantic and Florida Bay.
Islamorada (Spanish for "Purple Isle") stretches across six islands between mile markers 73 and 90, roughly 75 miles south of Miami. Its claim as the "Sport Fishing Capital of the World" is well-earned — the unique geography places anglers within a short boat ride of three completely different fisheries: the Atlantic offshore reef and blue water, the nearshore patch reefs and wrecks, and the shallow backcountry flats of Florida Bay.
But Islamorada is far more than fishing. The Florida Reef Tract — the only living coral barrier reef in the continental United States — runs along the Atlantic side 4–6 miles offshore, hosting spectacular snorkeling and diving. The backcountry of Florida Bay offers some of the finest kayaking and paddleboarding in the state, with mangrove tunnels, crystal flats, and abundant wildlife including manatees, dolphins, and dozens of bird species.
The Florida Reef Tract off Islamorada is part of the Florida Keys National Marine Sanctuary and the third-largest coral barrier reef system in the world. Popular snorkel and dive sites include Cheeca Rocks (just 1 mile offshore), the Alligator Reef Lighthouse (6 miles offshore), Davis Reef, Crocker Reef, and the San Pedro Underwater Archaeological Preserve — a 1733 Spanish shipwreck at 18 feet depth covered in corals and teeming with fish.
Boat rentals for self-guided exploration of Islamorada's waters — Florida Bay backcountry, nearshore reefs, and the Intracoastal Waterway. Perfect for fishing, snorkeling, or cruising between the island chain's turquoise flats and mangrove shorelines.

Islamorada's backcountry flats — the vast shallow grass beds of Florida Bay visible from the Overseas Highway — are considered among the finest fly fishing and light tackle destinations on earth. Guides pole specialized shallow-draft skiffs across water that may be only 12–18 inches deep, stalking bonefish (nicknamed "the ghost of the flats"), permit, and migrating tarpon. The annual tarpon migration brings massive silver kings — 80 to 150+ pound fish — stacking in the passes and channels from April through June. Booking a guide well in advance (months ahead during peak season) is essential.
Islamorada sits within John Pennekamp Coral Reef State Park's extended zone and the Florida Keys National Marine Sanctuary. Cheeca Rocks, just one mile offshore in only 12 feet of water, is one of the most accessible and productive reef snorkeling sites in the Keys — healthy coral formations surrounded by parrotfish, angelfish, grouper, and moray eels. The Alligator Reef Lighthouse marks a dramatic offshore reef system at 5–6 miles with exceptional diving. The San Pedro shipwreck, a 1733 Spanish galleon at 18 feet depth, is an easy snorkel with remarkable history.
The Florida Bay side of Islamorada offers some of the most beautiful flatwater paddling in Florida. Mangrove-lined channels, open grass flats reflecting the sky, and abundant wildlife make this a world-class kayaking destination. Indian Key Historic State Park — accessible only by water — is a highlight: the ruins of a 19th-century town on a small island surrounded by pristine reef. Anne's Beach and Indian Key Fill offer easy put-in access for self-guided paddles into the backcountry.
Florida spiny lobster season runs August 6 through March 31 (with a 2-day sport season in late July). Islamorada's reefs and patch reefs hold significant lobster populations, and diving for lobster is a beloved local tradition. The animals live under ledges and in reef crevices, typically at 10–30 feet depth — accessible to snorkelers and scuba divers alike. Many charter operators run dedicated lobster diving trips during season, providing tickle sticks and nets for catching your limit.
Because of the extraordinary variety and quality of fishing accessible from a single location — backcountry flats for bonefish, permit, and tarpon; nearshore reefs for grouper and snapper; and Atlantic blue water for sailfish, mahi-mahi, and wahoo. The holy trinity of fly fishing (bonefish, permit, tarpon) is available within the same area, which is almost unmatched anywhere in the world.
Most of Islamorada's best snorkeling requires a short boat ride to reach the offshore reefs (4–6 miles out). However, some shore snorkeling is possible at Anne's Beach and around the bridges. For the best reef experience, joining a guided snorkel tour to Cheeca Rocks or Alligator Reef is strongly recommended — the difference in coral health and fish abundance between shore and reef sites is dramatic.
Islamorada is approximately 75 miles south of Miami — about 90 minutes to 2 hours by car via US-1 through the Keys. It's a popular day trip destination from Miami, though spending at least one night allows for early-morning fishing tides and sunset on the Bay side. The drive through the Keys on the Overseas Highway is itself one of Florida's most scenic routes.
April through June is peak tarpon season when large migratory tarpon (80–150+ lbs) stack in the channels and passes around Islamorada. The spring tides move massive schools of fish through predictable routes, giving guides and anglers the chance to sight-cast to rolling tarpon. This is considered the pinnacle of Keys fishing and guides book up months in advance for prime April–May dates.
