Île de Ré is an island off the west coast of France. It’s known for its salt marshes and beaches like the Plage de la Conche des Baleines, backed by dunes and pine trees. Nearby, the Phare des Baleines is a lighthouse offering expansive views. The main town of St-Martin-de-Ré has the 17th-century Fortifications of Vauban, plus outdoor cafes overlooking the marina. Bicycle paths crisscross the island.
