Cilaos is a remarkable spa village hidden within one of La Réunion's three great volcanic cirques — ancient calderas created by the collapse of the island's ancient shield volcano — accessible via one of the most spectacular mountain roads in the Indian Ocean, with 400 hairpin turns climbing to a basin ringed by the dramatic peaks of the Piton des Neiges massif. The oligomineral spring water of Cilaos, once bottled commercially, and the village's historic thermal traditions attract visitors seeking a natural wellness experience combined with the extraordinary landscape of the UNESCO-listed 'Pitons, cirques and remparts' World Heritage site. The cirque's isolation, extraordinary endemic flora, world-class hiking to Piton des Neiges (the highest point in the Indian Ocean), and unique Creole culture make Cilaos one of the most remarkable and little-visited destinations in the entire French overseas territory network.

Insider tip — La Réunion's oligomineral springs are worth the trip: Cilaos is the jewel at 35°C.
