Cayo Costa State Park occupies a largely undeveloped barrier island off Florida’s Gulf Coast, valued for its long white-sand beach, varied interior habitats, and abundant wildlife, including nesting sea turtles, dolphins, manatees, and coastal birds. Reachable only by boat or ferry, it preserves natural landscapes along islands that shelter Charlotte Harbor and Pine Island Sound. The island also holds a deeper human history: the Calusa lived here until about 1700, Cuban fishing ranchos operated in the area from the early 18th century, and Tervio Padilla, known as Captain Pappy, later ran a fishing rancho here. Graves on the island, including victims of the 1910 hurricane, connect its quiet setting to a harder maritime past.
