10 Secret Florida Islands You Can Only Reach by Boat
Florida is known for its stunning beaches and island getaways, but some of its most beautiful spots are hidden away, only accessible by boat. These secluded islands offer pristine beaches, untouched nature, and a peaceful escape from the crowds.
If you’re looking for an off-the-beaten-path adventure, here are 10 secret Florida islands you can only reach by boat.
1. Cayo Costa
Located off the Gulf Coast near Fort Myers, Cayo Costa is a hidden paradise with white sandy beaches, clear blue waters, and abundant wildlife. The island is a state park, meaning it’s completely undeveloped, making it perfect for camping, shelling, fishing, and hiking. It’s only accessible by private boat or ferry, keeping it one of Florida’s best-kept secrets.
2. Keewaydin Island
Just south of Naples, Keewaydin Island is a secluded, boat-access-only island known for its unspoiled beaches and relaxed vibe. Unlike many Florida islands, there are no roads, bridges, or cars—just pure nature. Locals and boaters love to visit for its soft sand, great shelling, and crystal-clear waters. A few floating food boats even serve snacks and drinks to visitors.
3. Egmont Key
Situated at the mouth of Tampa Bay, Egmont Key is a small, historic island with an abandoned military fort, a working lighthouse, and stunning beaches. The island is part of a wildlife refuge, home to gopher tortoises and seabirds. Visitors can explore the ruins, snorkel around the rocky shoreline, or simply enjoy the peace and quiet.
4. Honeymoon Island State Park (North End)
While the main part of Honeymoon Island is accessible by car, the northern section remains completely wild and boat-access-only. It’s an untouched stretch of sand, perfect for those looking to escape the crowds. Kayakers and boaters love to explore this area for its birdwatching, beautiful beaches, and peaceful atmosphere.
5. St. Vincent Island
Located in the Florida Panhandle near Apalachicola, St. Vincent Island is a national wildlife refuge known for its diverse ecosystems and wild beauty. The island is home to bald eagles, red wolves, and even exotic Sambar deer. Visitors can enjoy hiking, fishing, and shelling on its remote beaches, but since it’s only accessible by boat, it remains uncrowded and serene.
6. Little Gasparilla Island
A true hidden gem, Little Gasparilla Island sits off the southwest coast of Florida, near Charlotte Harbor. With no bridges or cars, the island offers a peaceful, old-Florida feel.

7. North Captiva Island
Unlike its more developed neighbor, Captiva Island, North Captiva is only accessible by boat or private plane.

Visitors can enjoy shelling, birdwatching, and exploring nature trails without the crowds.
8. Cedar Keys National Wildlife Refuge
This cluster of small islands off Florida’s Nature Coast is part of a protected wildlife refuge. Once home to a thriving fishing community, the islands are now nearly deserted, providing an incredible getaway for nature lovers. Kayakers and boaters can explore the winding waterways, spot dolphins, and enjoy the stunning scenery.
9. Shell Key Preserve
Located near St. Pete Beach, Shell Key Preserve is an undeveloped barrier island known for its pristine beaches, excellent birdwatching, and crystal-clear waters.
