Sanibel and Captiva, FL

Sanibel and Captiva are two low-key barrier islands off the Lee County coast in Southwest Florida, reached by the Sanibel Causeway. They are known for some of the best shelling in North America, miles of bike paths and wildlife refuges that cover much of the islands.

Where are Sanibel and Captiva?

The islands lie in the Gulf just off Fort Myers. Southwest Florida International Airport (RSW) is about 45 minutes from Sanibel, and longer to the north end of Captiva. The three-mile Sanibel Causeway starts at Punta Rassa and carries a toll for vehicles heading onto the island only. A short bridge over Blind Pass connects Sanibel to Captiva.

Things to do on Sanibel and Captiva

Shelling comes first. Sanibel’s east-west shape catches shells carried in by the tides, and the bent-over search for them even has a name, the Sanibel stoop. Bowman’s Beach is a favorite, Lighthouse Beach Park sits at the east end beside the 1884 Sanibel Lighthouse and a fishing pier, and Blind Pass Beach straddles the two islands. On Captiva, Alison Hagerup Beach Park and Turner Beach are popular sunset spots. Parking is paid and lots fill early.

J.N. “Ding” Darling National Wildlife Refuge protects more than 6,400 acres of mangroves and tidal flats. Its four-mile, one-way Wildlife Drive is best at low tide for wading birds and is closed on Fridays. The Bailey-Matthews National Shell Museum and Aquarium covers the science behind what you find on the beach. Many visitors trade the car for a bike once they arrive, using the island’s shared-use paths.

Hurricane Ian badly damaged the islands and the causeway in 2022. Most beaches and the refuge have reopened, but some properties and trails are still being rebuilt.

When to visit Sanibel and Captiva

Winter and spring bring the best weather and the heaviest causeway traffic, so start early. Shelling is often best after winter cold fronts and at low tide. Summer is quieter, with sea turtle nesting season on the beaches.
