The Causeway Islands are a series of islands that link Sanibel Island to the Florida mainland. They bisect San Carlos Bay a short distance from the mouth of the Caloosahatchee River, and allow bay and gulf side access. These beaches are prime real estate for every beach going activity including picnicking, windsurfing, shelling, swimming, fishing and more. There are restrooms at select beaches and plenty of beach to choose from.

There is no parking fee and you can pull your vehicle right up to the waters edge on either side of the road. Very popular with locals, so expect a large crowd on holidays and weekends.

The Causeway Islands are open from 7 a.m. to dusk, seven days a week
