12 Hidden Islands In Florida You Need To Explore
The first time I followed a vague tip onto a tiny Florida ferry, I half suspected I was sailing straight off the edge of the guidebook.
Somewhere between the mainland and a strip of sand I had never heard of, my phone signal faded, my to-do list dissolved, and my only real concern became whether my sandals would survive the landing.
Since then, I have started treating Florida’s hidden islands as a personal scavenger hunt, chasing whispers about sandbars, old forts, and mangrove tunnels that never make it onto billboards.
On these trips, I trade parking garages for pilings, traffic reports for tide charts, and souvenir shops for a cooler, a hat, and whatever snacks I remembered to grab on the way out the door.
More than once, a captain has pointed toward a patch of low greenery and casually said, “That is your stop,” and I have stepped onto sand where the only crowd is a cluster of shorebirds.
These islands have a talent for shrinking the world down to waves, wind, and the occasional dolphin that refuses to stick to the schedule.
Friends still assume Florida is all highways, high-rises, and shoulder-to-shoulder beaches, and I keep answering with stories about places you can only reach by boat, kayak, or sheer stubborn curiosity.
If you are ready to swap packed shorelines for quiet coves and want your next Florida trip to feel a little more secret, these twelve hidden islands are exactly where I would start.
1. Shell Key Preserve, Tierra Verde
Some of my quietest Florida moments start with a boarding pass in my pocket and Shell Key on my mind.
I head for the Shell Key Shuttle at Merry Pier, 801 Pass A Grille Way, St Pete Beach, FL 33706, where the dockside chatter always feels one notch more relaxed than the mainland.
By the time the boat noses up to the sand, I am already scanning for shorebirds, sand dollars, and a patch of beach that feels temporarily mine.
This undeveloped barrier island usually trades loud music for the softer sounds of waves, seabreeze, and distant gulls.
I like to wander toward the quieter ends of the shoreline, where footprints thin out, and the shells get more interesting.
Sometimes I bring a simple picnic and a book, then realize I have barely opened it because the water keeps stealing my attention.
On days when the tide cooperates, I walk the curve of the island until the boat looks tiny and the mainland feels very far away.
Every return ride gives me that smug little thrill that I spent the afternoon on a sandbar most drivers on nearby roads never actually see.
2. Caladesi Island State Park, Dunedin
One of my favorite winter tricks is to park in busy Dunedin and vanish onto Caladesi Island a short ferry ride later.
To pull off that disappearing act, I drive to the Honeymoon Island ferry dock at 1 Causeway Blvd, Dunedin, FL 34698, and hop the passenger boat over to Caladesi’s quieter side.
The ride is short enough to feel easy and long enough to reset my brain before my feet hit the sand.
Once I land, I usually follow the boardwalk toward the long beach and watch the shells, shorebirds, and distant kayakers slowly sort the crowd into smaller pockets.
There is a mangrove-lined paddling trail for days when I feel energetic and a shaded picnic area for the exact opposite mood.
I like slipping onto the nature trail, where the wind through the pines and oaks feels different from the open shoreline breeze.
Caladesi tends to reward people who keep walking, and I have more than once found stretches of sand where there are more pelicans than people.
By the time the ferry carries me back to the causeway, I always feel slightly surprised to see cars again.
3. Anclote Key Preserve State Park, Offshore Tarpon Springs
Every time I head toward Tarpon Springs, there is a part of me already plotting how to escape to Anclote Key for a few hours.
This low-key island sits about three miles offshore, officially listed with the simply mysterious address Offshore Tarpon Springs, FL 34689, which already hints that roads will not help you much.
I usually book a boat tour or hop a local shuttle from the river, watching the sponge docks fade as blue water takes over.
When the boat nudges up near Anclote’s beaches, the lighthouse at the southern end feels like a quiet timekeeper watching gulls instead of traffic.
I have spent long afternoons here doing very little beyond swimming, walking the flat shoreline, and seeing how many shapes I can spot in the cloud line.
On calmer days, I wade out just far enough to feel the sand shift under my toes while dolphins occasionally cruise past in the distance.
Camping is possible for people who plan ahead and do not mind trading city lights for stars and shore sounds.
Because tropical weather reshapes these sands from time to time, I always check local conditions and boat schedules before committing my daydreams to the dock.
4. Egmont Key State Park, Near St. Pete
Whenever I want history and solitude to share the same patch of sand, I aim my morning toward Egmont Key.
To reach it, I make my way to the ferry at Fort De Soto Park’s Bay Pier, using 3500 Pinellas Bayway S, Tierra Verde, FL 33715, as my driving target.
The ride out passes between tankers and dolphin splashes until the low island and its old brick fort finally come into focus.
I like starting with a slow wander through the fort ruins and lighthouse area, where the paths meander between weathered bricks and scrubby vegetation.
After I get my history fix, I usually drift toward the beaches on the Gulf side, where the water tends to look extra clear over the sand.
Sea turtles, gopher tortoises, and a whole crowd of seabirds treat this place like a neighborhood, so I tread carefully and give them priority.
Snorkelers often float along the shallows near the pilings, and I have spent more than one hour just watching schools of fish weave around old structures.
By the time the return boat pulls away, the St. Pete skyline feels oddly busy compared with the quiet little island we just left behind.
5. Keewaydin Island, Marco Island
On days when paved streets feel overrated, I point the car toward Marco Island and set my sights on Keewaydin’s long stretch of sand.
My launchpad is Rose Marina, where the Hemingway Water Shuttle departs at 951 Bald Eagle Dr, Marco Island, FL 34145, and turns a regular afternoon into a mini crossing.
The ride threads through mangrove channels and open water, and I have lost count of how many dolphins have paced the boat along the way.
Once my feet hit the island, the lack of roads, buildings, and honking feels like someone turned the background volume knob down several clicks.
I usually walk away from the busier landing area until I find a patch of beach where it is just me, sea oats, and waves.
Shell hunters adore this place, and I have had days when my pockets turned into clinking evidence of very ambitious beachcombing.
There are no permanent facilities, so I pack everything I need and treat every wrapper and bottle like a boomerang that must return with me.
By the time the shuttle picks me up, the mainland always feels slightly less urgent than it did a few hours earlier.
6. North Captiva Island, Lee County
Sometimes I crave a destination where golf carts outnumber cars, and the only traffic report I care about involves tides.
To reach North Captiva, I board the Island Girl Charters ferry at Pineland Marina, 13921 Waterfront Dr, Bokeelia, FL 33922, and watch the mangrove fringe slide past on the crossing.
The ride is short, but it feels like enough distance to leave grocery lists and email pings safely behind on the mainland.
When I arrive, sandy lanes and low-key houses give the island a beach-town feel with the volume turned gently down.
I like renting a golf cart or hopping on a bike to explore the shoreline access points and quiet corners.
Some stretches of beach feel so uncrowded that I start counting pelican dives instead of people.
On windy days, watching the whitecaps line up across Pine Island Sound becomes its own kind of entertainment.
By the end of the day, the return ferry feels less like a simple transfer and more like a gentle decompression chamber back toward reality.
7. Cayo Costa State Park, Island South of Boca Grande
Whenever I want Florida to feel truly wild, I aim my plans toward Cayo Costa and its long, undeveloped shoreline.
This barrier island sits south of Boca Grande, officially tagged as Cayo Costa State Park, Island South of Boca Grande, Boca Grande, FL 33921, and it insists that visitors arrive by boat.
I usually arrange a trip by private boat or charter, then watch as marinas shrink behind us and nine miles of quiet beach slowly appear ahead.
Once ashore, I like following sandy paths through pines and palms until the sound of the Gulf takes over.
Shelling here can be excellent, and I have had mornings where every few steps uncovered another color or spiral worth admiring.
Dolphins, manatees, and plenty of shorebirds frequently patrol this coastline, so I keep my eyes open and my camera ready.
Because Hurricane Ian reshaped much of this area and ferry services and amenities have seen changes, I always check current park and boat updates before I go.
When the boat finally pulls away in the late afternoon, the island’s low profile makes my whole visit feel like a secret I almost imagined.
8. Cabbage Key, Near Bokeelia
On days when I want my island time small-scale and story-filled, I set my course toward Cabbage Key.
This little spot sits in Pine Island Sound and centers around Cabbage Key Inn and Restaurant, 13771 Waterfront Dr, Bokeelia, FL 33922, which doubles as both a landmark and a lunch option.
Getting there usually involves a scenic boat ride from Pineland or nearby marinas, with ospreys and dolphins often putting on the real show.
Once I step onto the island, the pace drops to the speed of lazy lizards sunning themselves on warm railings.
I like circling the nature trail, climbing small rises for views over the sound, and listening to the wind work its way through the trees.
Pelicans perch on pilings around the docks, occasionally rearranging themselves as boats glide in and out.
Afternoons tend to drift by easily here, especially if I tack on a bit of dock-sitting and boat-watching after lunch.
Heading back across the water, I always feel like I have visited the neighborhood hangout for boats rather than cars.
9. Atsena Otie Key, Cedar Key
When my road trip carries me up to Cedar Key, I secretly hope the weather cooperates so I can slide over to Atsena Otie.
My usual starting point is along the waterfront near the tour boats at 302 Dock St, Cedar Key, FL 32625, where captains shuttle visitors across the short stretch of water.
The ride barely lasts long enough to finish a story, yet it still manages to feel like a proper crossing.
Atsena Otie holds old ruins, shaded trails, and a sense that time decided to stroll instead of sprint here.
I like wandering under the trees, reading the small bits of history, and then emerging onto the shell-strewn shoreline.
Birdlife tends to be busy along the edges, from herons stalking the shallows to pelicans coasting overhead.
Because tides and weather matter more than timetables in this part of Florida, I keep an eye on both before and during my visit.
By the time the boat takes me back to Cedar Key’s stilted buildings and seafood spots, the mainland feels more like an extension of the islands than the other way around.
10. Indian Key Historic State Park, Islamorada
Sometimes I like my hidden islands with a side of history and a requirement that I earn them with a paddle.
Indian Key Historic State Park sits off Islamorada in the Upper Keys, officially listed along the Overseas Highway as Indian Key Historic State Park, Overseas Hwy, Islamorada, FL 33036, and it is reached by boat or kayak.
I usually launch a kayak near mile marker 79 and follow the shallow flats until the little island rises ahead of me.
Once I land, old foundations, interpretive signs, and quiet paths tell stories about earlier residents who bet their lives on this sand patch.
The water around the island stays clear enough that fish, rays, and occasional sharks become part of the supporting cast for every walk.
I like pausing near the small observation tower, which currently stays closed due to storm damage, and taking in the wide views of turquoise water and scattered mangrove clumps from the nearby shoreline instead.
On still days, the silence is broken mostly by wind, distant boat engines, and the creak of my own footsteps.
Kayaking back toward the Overseas Highway, I always feel slightly amused that so many drivers rush past without realizing this little world sits just offshore.
11. Boca Chita Key, Biscayne National Park
Whenever Miami traffic frays my patience, I remember that an island with a lighthouse and zero stoplights sits just a boat ride away.
To set that escape in motion, I head for Biscayne National Park’s Dante Fascell Visitor Center at 9700 SW 328th St, Homestead, FL 33033, where park trips and tours often depart toward Boca Chita Key.
The boat ride moves from mangrove shoreline to open bay, with downtown Miami slowly shrinking into a jagged line on the horizon.
Boca Chita’s small harbor feels snug once we pull in, especially with the historic lighthouse standing guard over the boats.
I like walking the short paths around the island, scanning for iguanas, birds, and the best angle on the skyline across the water.
Picnic tables and grassy patches make it easy to claim a temporary corner and watch the light change on the bay.
On calm days, the water around the island turns so clear that I can see fish flickering between patches of seagrass.
By the time the boat brings me back to the visitor center, the traffic on nearby roads seems oddly unimportant compared with those few quiet hours.
12. Garden Key, Dry Tortugas National Park
When I really want to feel far from Florida without leaving the state, I start plotting a trip to Garden Key in the Dry Tortugas.
The adventure begins at the Yankee Freedom III terminal at 100 Grinnell St, Key West, FL 33040, where the ferry loads up for the long run, seventy miles west.
The crossing takes a few hours and trades Key West buildings for open Gulf water and, eventually, a brick fort ringed by blue.
Once on Garden Key, Fort Jefferson dominates the view, and I like circling the moat wall before ducking into its echoing brick corridors.
When the history itch is scratched, I usually grab snorkel gear and slide into the water near the designated swim areas.
Coral, fish, and shifting light around the fort’s old pilings turn the shallows into a busy underwater neighborhood.
Between swims, I wander the narrow beaches and watch frigatebirds and other seabirds trace long, lazy routes overhead.
As the ferry finally points back toward Key West, I always catch myself looking over my shoulder, already thinking about when I might return to that brick ring in the middle of the Gulf.
