Tortuga is a rocky, mountainous island in Haiti, just off the northern coast of the mainland. The fishing port of Basse-Terre, on the island’s south coast, is home to the ruined 17th-century Fort de Rocher, once a pirate stronghold. In the east, one of the island’s caves, Grotte au Bassin, has a large pre-Columbian sculpture of a woman. Beaches include Pointe Ouest, at the western tip, with wide white sands.
