Cayo Costa State Park is a Florida State Park on Cayo Costa (formerly known as La Costa Island), which is directly south of Boca Grande (Gasparilla Island), 12 miles (19 km) west of Cape Coral and just north of North Captiva Island. The park is accessible only by charter boat (with or without captain), private boat, ferry or helicopter.

Cayo Costa Island is one of a chain of barrier islands that shelter Charlotte Harbor and Pine Island Sound. The park contains nine miles (14 km) of soft white sandy beaches and 2,506 acres (10 km2) of pine forests, oak-palm hammocks, and mangrove swamps.

There are 12 primitive cabins and 30 tent sites available for camping each with its own picnic table and fire pit/ground grill assigned to each site. Boat slips are available for those who wish to camp aboard their boats.
