Cayo Costa State Park is a 2,506-acre barrier island in Lee County, Florida, between Gasparilla Island and North Captiva Island, with nine miles of undeveloped Gulf beach and no bridge or public road access. You reach it only by private boat, charter, or passenger ferry — most commonly from Pineland on Pine Island or Punta Gorda — and once there you'll find hiking and biking trails, 12 primitive cabins, 30 tent sites, and almost none of the crowds found on Sanibel or Fort Myers Beach.
Sanibel gets the shell-seekers, Boca Grande gets the tarpon anglers, and Fort Myers Beach gets everyone else — but ask a Southwest Florida local where the best beach actually is, and a fair number will point you south of Boca Grande to an island you can't drive to. Cayo Costa State Park is nine miles of undeveloped Gulf shoreline with no hotels, no beach bars, no cars, and no bridge. The only way onto it is by water, which is exactly why it's stayed close to how it looked before any of the barrier islands around it were developed.
It sits in Lee County between Gasparilla Island to the north and North Captiva Island to the south, part of the same Pine Island Sound and Charlotte Harbor barrier chain visible from Seaside Boca, our Placida home about a 15-minute drive from the ferry launch points.
How do you actually get to Cayo Costa?
- Passenger ferry — the longest-running option runs from Pineland Marina on Pine Island, roughly a half-hour drive from Placida and Boca Grande, with the boat operator handling the roughly 30–45 minute crossing through Pine Island Sound.
- Private boat — Cayo Costa has boat slips and a dock on the bay side, reached via the Intracoastal Waterway and Pine Island Sound; local knowledge of the shallow flats around the island matters here as much as it does approaching Don Pedro Island or Gasparilla.
- Charter — several Pine Island and Boca Grande operators run charter trips to the island with or without a captain, useful if you don't own a boat and want more flexibility than a fixed ferry schedule.
- There is no vehicle access of any kind. If a trip doesn't include a boat, a ferry ticket, or a charter booking, it isn't a Cayo Costa trip.
No hotels, no beach bars, no cars, and no bridge — the only way onto it is by water.
What's actually on the island?
Once you're off the boat, a tram or a roughly 15–20 minute walk from the bayside dock crosses the island to the Gulf beach — nine miles of it, mostly empty even on a busy weekend, good for swimming, shelling, and snorkeling along the tide line. Inland, the park has hiking and off-road biking trails through pine flatwoods and coastal scrub, a small nature center, and a historic cemetery from the island's Cuban fishing-rancho era, where roughly 30 fishermen who died in the 1910 hurricane are buried alongside the family of Captain Francisco "Pappy" Padilla, who ran a fishing camp here in the 19th century. The park has taken direct hits from Hurricane Charley in 2004 and Hurricane Ian in 2022, both of which reshaped parts of the shoreline and vegetation you'll see today.
For overnight visitors, the park has 12 primitive wooden cabins — each furnished with bunk beds and a table, no electricity — and 30 tent camping sites, all requiring advance reservations. There's no restaurant or store on the island beyond a small concession that isn't always open, so this is a pack-in trip: water, sunscreen, and food for the day, or for the length of a camping stay.

What does it cost, and when is it open?
The park itself is open daily, 8 a.m. to sunset, for anyone arriving by private boat. Ferry and charter operators set and periodically adjust their own pricing separately from the park entrance fee, and — like several barrier-island parks in this region — Cayo Costa's ferry service, camping availability, and facilities have been affected at times by hurricane recovery and infrastructure work. Confirm current ferry departure points, prices, and whether camping and cabin reservations are open before you build a trip around this island; floridastateparks.org and the individual ferry/charter operator are the sources to check, not a general search result or a guide written months earlier.
Who is this trip actually right for?
Families who already have a boat, or who're comfortable booking a ferry or charter and building the day around a fixed departure and return time. It's a strong fit for older kids who can handle a beach walk and a boat ride, and for anyone who's already done the drive-up beaches at Boca Grande or Englewood and wants the undeveloped version. It's a harder fit for families with a stroller, very young toddlers who nap on a schedule, or anyone who needs the flexibility to leave on short notice — a ferry or charter runs on its own timetable, not yours.
When is the best time to go?
- Fall through spring brings calmer water for the boat crossing and more comfortable temperatures for the walk across the island to the beach.
- Morning departures beat afternoon ones — Southwest Florida's summer thunderstorms build through the afternoon and can affect both the crossing and the return trip.
- Loggerhead and green sea turtle nesting runs March through October, adding wildlife interest to a summer trip along with the heat and storm risk.
- Book ferry, charter, or camping reservations well ahead in season — none of these are a reliable walk-up option, especially after storm season when schedules can shift.
Where should a family base for this trip?
Placida and Boca Grande sit closer to the Pineland and Punta Gorda ferry launch points than most other lodging bases in the region, and that's exactly where Seaside Boca is — our Key West-style home in Cape Haze near Boca Grande, sleeping 10 across 3 bedrooms plus a bunk room and 3.5 baths, with a resort-style pool, hot tub, infrared sauna, private mini golf, and dock access. If your family is bringing your own boat for the Cayo Costa crossing, the dock here lets you stage gear the evening before and be underway early, ahead of the afternoon wind and storm buildup.
For the beaches you can simply drive to on the same trip, see our guides to Gasparilla Island State Park and the Englewood vs. Boca Grande beach comparison. If your group is weighing this trip against another boat-only barrier island nearby, our Don Pedro Island State Park guide covers the closer, shorter-crossing alternative. And for the mainland context around where you're staying, see our Port Charlotte, Placida, and Cape Haze guide.
Cayo Costa State Park questions families ask
Can you drive to Cayo Costa State Park?
No. Cayo Costa has no bridge or public road of any kind. The only ways to reach it are private boat, a chartered boat, or a passenger ferry, most commonly departing from Pineland on Pine Island or from Punta Gorda.
How big is Cayo Costa State Park?
The park covers 2,506 acres and includes nine miles of undeveloped Gulf beach, making it the longest stretch of unbuilt natural shoreline among the barrier islands in this part of Southwest Florida.
Can you camp on Cayo Costa?
Yes — the park has 30 tent camping sites and 12 primitive wooden cabins with bunk beds and no electricity, all requiring advance reservations. Confirm current availability directly with Florida State Parks before planning an overnight trip.
Is Cayo Costa good for families with young kids?
It works best for families comfortable with a fixed ferry or charter schedule and a beach walk from the dock. Families with strollers, very young toddlers, or nap schedules to protect generally do better at drive-up beaches like Boca Grande or Englewood.
What's the closest town to base a Cayo Costa trip from?
Boca Grande and Placida sit closer to the main Pine Island and Punta Gorda ferry launch points than most other lodging areas in the region, making them a practical base for a Cayo Costa day trip.
