A unique mixture of coastal and tropical hammock and mangrove forest, this barrier island provides a haven for several rare or endangered native tropical and coastal plant species. The park's Nature Center shows visitors why the park is a biological treasure. Visitors can swim, picnic, and surf at the beach; scuba diving and snorkeling are also popular activities. Birdwatchers can see herons, brown pelicans, terns, sandpipers, and gulls. Anglers can fish in the lagoon by wading, kayaking, or canoeing. They can also fish from non-swimming areas of the beach.
