Lucayan National Park is on Grand Bahama Hwy. The 40-acre (16-hectare) park contains one of the largest explored underwater cave systems in the world. Ecological zones in the park include upland pineland with hardwood hammocks, rocky coppice, whiteland coppice, mangrove marshes and sand dunes. A 1-mile trail and boardwalk leads to Ben's Cave, Burial Mound Cave, Gold Rock Creek and Gold Rock Beach.
Swimming in the caves is prohibited; diving requires special permits.
