Fort Napoléon crowns the hill above Terre-de-Haut's village, reached by a steep path that takes about 20 minutes from the waterfront. Built in the 19th century to commemorate the 1782 naval Battle of Les Saintes, it was never attacked — the era of Caribbean island fortifications was essentially over by the time it was completed.
The fort houses a museum of the battle and local natural history, but the main reason to make the climb is the panoramic view from the ramparts: the bay, the islands of the archipelago, and on a clear day, Guadeloupe and Dominica in the distance. A cactus garden within the walls has been developed by the botanical association. The walk up is worth it even if the museum doesn't hold your attention — the view alone justifies the admission.
