Andros Island is The Bahamas' natural wonder. The earth's third-largest barrier reef lies adjacent to its shores and fascinates divers and snorkelers with magnificent whales, dolphins, marlin and reef animals. Underwater caves riddle the island, surfacing as mesmerizing blue holes; mangroves serve as relaxing environs for kayaking; flats make the island sought after for bonefishing; and forests delight avid bird watchers with exotic species.
