No mountain pair is as famous as the Saint Lucia Pitons, the island’s iconic mountains. The Pitons are protected as a UNESCO World Heritage site, the dramatic twin peaks of Gros Piton and Petit Piton are among the Caribbean island’s most memorable landmarks. Towering 2,619 feet (798 meters) above sea level, the Gros Piton, the larger of the two, is also a popular challenge for avid hikers. They do resemble a pair of Megalodon shark tooth.
