Réunion is a French overseas region and department in the Indian Ocean, 700 km east of Madagascar and 200 km south-west of Mauritius. This volcanic island of extraordinary drama packs an active volcano, three steep-walled cirques, a UNESCO World Heritage mountain core, dense rainforest, and a warm lagoon into 2,512 km². It is simultaneously French enough to accept euros and credit cards everywhere, and exotic enough to feel like another world entirely.
