Guadeloupe is an overseas department and region of France in the Caribbean, shaped like a butterfly formed by two main islands — volcanic Basse-Terre to the west and coral-limestone Grande-Terre to the east — connected by a narrow channel crossed by the Rivière Salée. Together with outer islands Les Saintes, Marie-Galante, and La Désirade, it offers volcanic hikes, world-class snorkeling, rum distillery tours, and sun-drenched beaches, all wrapped in an authentically French Caribbean culture.
