After being twice enlarged, once in 1974 and again in 1980, the waters surrounding the northernmost coral reef in North America became a full-fledged national park. There's not much for landlubbers here. The park's small mainland mangrove shoreline and 44 islands are best explored by boat. Its extensive reef system is popular with divers and snorkelers. The concessionaire at Convoy Point rents canoes, runs dive trips, and offers popular glass-bottom boat tours.
All campsites have a picnic table and a grill.
Overnight tie-ups for boats, tent camping in designated areas, rest rooms, picnic tables, grills, and a short nature trail. Fresh water is not available, and all trash must be packed out. Snacks, juice, and soft drinks are available in vending machines. Food stores and supplies are not available in the park but can be purchased in nearby Homestead. Boaters may spend the day or night.
