Tucked beneath the Superbagnères massif, the resort town of Bagnères-de-Luchon owes its fame to sodium sulphur waters, among the most sulphur-rich in Europe. Already used in Gallo-Roman times around the settlement of Ilixon, these hot waters emerge after a long underground journey through Pyrenean granite. It was in the 18th century that Baron d'Étigny launched the town's development, laying the groundwork for what would become known as the "Queen of the Pyrenees".
The arrival of the railway in 1873 cemented Luchon's status as a must-visit destination for spa culture and early Pyrenean mountaineering. The site preserves a unique legacy in its Vaporarium: former Roman galleries stretching 1,200 metres, fitted out in 1929, where natural sulphurous vapours drift through the bare rock, said to form Europe's only natural steam cave. A place where ancient history and Pyrenean way of life meet.
