Florida is blessed with more than sunshine and theme parks — it’s a gateway to some of the most stunning islands in the United States and even beyond. The islands near Florida range from coral cays surrounded by turquoise waters to peaceful Gulf Coast getaways and even foreign islands just a short boat ride away. Whether you’re dreaming of snorkeling above vibrant reefs, collecting seashells on quiet beaches, or exploring historic forts, there’s an island destination for every traveler. This guide will help you discover the best islands near Florida, what makes them unique, and the top things to do when you visit.
1. The Florida Keys – America’s Coral Paradise
Stretching more than 110 miles from Miami to Key West, the Florida Keys are the most famous chain of islands near Florida. Connected by the scenic Overseas Highway, the Keys offer a tropical paradise without leaving the United States. Each island has its own character — from the dive spots of Key Largo to the lively streets of Key West.
Key Largo is known as the “Dive Capital of the World.” Its most iconic attraction, the John Pennekamp Coral Reef State Park, was the first undersea park in the U.S. Visitors can snorkel, scuba dive, or take glass-bottom boat tours to view the coral reefs and marine life. Moving further south, Islamorada proudly calls itself the “Sportfishing Capital of the World,” offering chartered trips for tarpon, sailfish, and mahi-mahi.
Marathon is perfect for families with its sandy beaches and the renowned Turtle Hospital, which rescues and rehabilitates injured sea turtles. Big Pine Key and the Lower Keys offer a slower pace, excellent for wildlife spotting and kayaking through mangrove tunnels. Finally, Key West is a lively blend of history, culture, and nightlife — home to Ernest Hemingway’s House, the Southernmost Point, and nightly sunset celebrations at Mallory Square. The Florida Keys truly showcase the best mix of adventure, relaxation, and coastal charm.
2. Dry Tortugas National Park – A Remote Natural Wonder
One of the most fascinating islands near Florida is Dry Tortugas National Park, located about 70 miles west of Key West. Accessible only by ferry or seaplane, this isolated park feels like a secret world lost in time. The centerpiece of the park is Fort Jefferson, a massive 19th-century brick fortress surrounded by crystal-clear waters and coral reefs teeming with life.
Visitors come here for world-class snorkeling, swimming, and photography. Because the Dry Tortugas are so remote, the water remains incredibly clear, and marine life is abundant. You can camp overnight on Garden Key — but with limited space, reservations are essential. Exploring the fort’s old corridors and then diving into the surrounding reef is an unforgettable experience that captures the raw beauty of nature. This hidden gem proves that some of the most breathtaking islands near Florida are also the least accessible.
3. Gulf Coast Islands – Serene Escapes on Florida’s West Side
While the Keys often steal the spotlight, the Gulf Coast of Florida hides several tranquil island destinations perfect for families and nature lovers. Sanibel and Captiva Islands, located near Fort Myers, are world-renowned for their shell-covered beaches. Every morning, visitors practice the “Sanibel stoop” — bending down to collect colorful shells washed ashore by gentle waves. Sanibel also hosts the J.N. “Ding” Darling National Wildlife Refuge, a sanctuary for migratory birds, dolphins, and manatees.
To the south, Marco Island blends natural beauty with resort luxury. As the largest of the Ten Thousand Islands, it’s a gateway to endless boating, fishing, and kayaking adventures. Just off Marco lies Keewaydin Island, accessible only by boat, offering untouched beaches and a truly peaceful atmosphere.
Further north, Anna Maria Island captures the nostalgic charm of “Old Florida.” With its small-town vibe, cozy beach cottages, and strict building codes that limit high-rises, Anna Maria is ideal for those seeking a quiet, authentic beach vacation. The island is also famous for its sea turtle conservation programs and stunning sunsets over the Gulf of Mexico.
4. Atlantic Coast Islands – History and Beachside Bliss
Florida’s Atlantic side also features a collection of scenic barrier islands with a mix of history and natural beauty. Amelia Island, near Jacksonville, is a favorite for travelers who enjoy a blend of culture and relaxation. The island’s historic town of Fernandina Beach features 19th-century architecture, boutique shops, and inviting cafes. The island’s long stretches of beach are perfect for horseback riding, while its state parks offer hiking and kayaking.
Further south, Anastasia Island near St. Augustine combines pristine beaches with a rich historical backdrop. Visitors can explore the nearby St. Augustine Lighthouse or enjoy surfing along the island’s protected coastline. The Atlantic islands are perfect for travelers who want a balance of relaxation, recreation, and historical exploration — all within easy driving distance of Florida’s mainland.
5. The Bahamas – Tropical Islands Just Off Florida’s Coast
Among the most enticing islands near Florida are those belonging to the Bahamas, just across the Florida Straits. The closest, Bimini, lies only about 50 miles east of Miami — a quick ferry or private boat ride away. Bimini has long been a favorite of anglers, divers, and writers like Ernest Hemingway, who found inspiration in its deep blue waters and relaxed island lifestyle.
The Bahamas offer a different flavor of island experience. You can snorkel through shipwrecks, relax on powdery beaches, or visit marine sanctuaries filled with colorful fish and coral. For Florida boaters, crossing to the Bahamas is an unforgettable adventure, but it’s essential to follow travel regulations — U.S. passports are required, and boaters must check in with customs using the CBP ROAM app upon returning to U.S. waters. The proximity of these Caribbean-style islands makes them a perfect international extension of any Florida trip.
6. Best Time to Visit the Islands Near Florida
Timing your visit can make all the difference when exploring the islands near Florida. The best months to visit are typically November through April, when the weather is warm but not excessively humid. This is the dry season, with calmer seas and cooler evenings — ideal for snorkeling, diving, or beach walks.
From June to November, the region enters hurricane season, bringing higher humidity and occasional tropical storms. However, this period also tends to be less crowded, with lower accommodation prices. If you plan a trip during this time, always monitor weather forecasts and purchase travel insurance for added peace of mind. Regardless of the season, Florida’s islands promise year-round sunshine and breathtaking coastal experiences.
7. Eco-Friendly & Responsible Island Travel
Preserving the fragile beauty of Florida’s islands is crucial. The coral reefs of the Keys, the sea turtle nesting grounds of the Gulf Coast, and the wildlife refuges along the Atlantic all depend on mindful tourism. When visiting, use reef-safe sunscreen to protect marine ecosystems, avoid touching coral or removing shells, and respect wildlife viewing guidelines. Many islands have active conservation programs, and supporting them through donations or volunteering helps ensure these natural wonders remain for future generations. Traveling responsibly not only protects the environment but also enriches your connection with the places you explore.
8. Planning Your Island Adventure
Choosing which islands near Florida to visit depends on your interests and travel style. For a road-trip adventure, drive the Overseas Highway through the Keys, stopping at different islands along the way. If you prefer quiet beaches and nature, head to Sanibel, Captiva, or Anna Maria Island. For history lovers, Amelia Island and Anastasia Island provide the perfect mix of stories and scenery. Those seeking remote exploration can plan a seaplane or ferry trip to the Dry Tortugas, while thrill-seekers and international travelers can take a quick hop over to Bimini or Grand Bahama.
Plan your trip with care — book ferries and accommodations early, especially in peak season. Bring sun protection, light clothing, and water gear, and always double-check entry or boating regulations if venturing beyond U.S. waters.
Conclusion
From the coral reefs of the Florida Keys to the quiet shores of Sanibel and the faraway charm of the Bahamas, the islands near Florida offer a remarkable variety of experiences. Each island has its own story — some vibrant and lively, others tranquil and untouched — but all share the same inviting sunshine and turquoise seas. Whether you’re diving into tropical reefs, exploring historic forts, or simply watching the sunset from a sandy beach, Florida’s islands promise adventure, beauty, and a deep sense of escape. These hidden gems prove that paradise doesn’t always require a passport — sometimes, it’s just a short drive or boat ride away
