Cayo Costa State Park is a 2,400-acre barrier island located along the Gulf of Mexico, accessible only by boat or ferry. The park features nine miles of undeveloped beach frontage characterized by high concentrations of seashells. Inland habitats include sand dunes, hardwood hammocks, and mangrove swamps that support diverse local wildlife. Visitors can traverse miles of trails designated for hiking and off-road biking. Overnight accommodations are restricted to primitive campsites and rustic cabins, requiring advanced reservations. Fresh water is limited, and the island lacks traditional vehicle roads, bridges, or electricity for general public use. The park serves as a critical nesting ground for loggerhead sea turtles during the summer months. Recent recovery efforts remain ongoing to repair infrastructure following significant impacts from past hurricane seasons.
