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; snorkeling is also a popular activity. Birdwatchers can see herons, brown pelicans, terns, sandpipers and gulls. Anglers can fish in the lagoon by wading or kayaking. Additionally, visitors can fish from non-swimming areas of the beach.
