Réunion is a French overseas department in the Indian Ocean, combining European infrastructure with tropical landscapes. The Piton de la Fournaise is one of Earth's most active volcanoes, its lava flows designated a UNESCO World Heritage Site. The western coast features the island's only coral lagoon, protecting beaches at Saint-Gilles-les-Bains, L'Ermitage, and Boucan Canot. Creole culture blends French, African, Indian, and Chinese influences—nowhere more evident than in the island's remarkable cuisine. The Euro is the currency; French the language.
