The islands were created primarily as a byproduct of dredging the San Carlos Bay channel to create a deeper route for marine traffic.
The causeway features a specific 'kite beach' zone designated for wind-dependent water sports.
The Sanibel Causeway was extensively reconstructed following the impacts of Hurricane Ian in 2022.
It is one of the few locations in the region where visitors can park their vehicles directly on the sandy beach surface.
The islands act as a protective barrier and transition point between the mainland and the sensitive Gulf Island ecosystem of Sanibel.
Causeway Islands Park consists of two man-made islands connected by the Sanibel Causeway, serving as the primary gateway to Sanibel Island. The park provides direct beach access along the San Carlos Bay, facilitating water activities such as swimming, fishing, and windsurfing. The islands are located within the Intracoastal Waterway, offering expansive views of the surrounding marine environment. Shoreline parking allows visitors to park their vehicles directly on the sand near the water's edge. The area is a popular destination for kiteboarding due to consistent bay winds. Visitors frequently observe dolphins and manatees in the shallow waters surrounding the causeway. The park serves as a public recreation area managed by Lee County, providing basic facilities including portable restrooms. It remains a focal point for birdwatching, specifically for shorebirds and raptors frequently perched on nearby pilings.
