Thermes de Luchon

Overview

Set in Bagnères-de-Luchon in the Haute-Garonne Pyrenees, the Thermes de Luchon draw on sulphurous thermal waters whose sulphur content the operator ranks among the highest in France and Europe. The waters are sodium-rich, alkaline and hyperthermal, rising from boreholes between roughly 170 and 730 metres deep at temperatures of 72 °C, 65 °C and 50 °C.

The Vaporarium

The spa's signature feature is its Vaporarium, a network of galleries carved directly into the rock. According to the operator, the sulphured Radio Vaporarium was created in 1929 and reveals some 1,200 metres of galleries, a natural hammam; the springs themselves were already used by the Romans. Visitors walk through a bath of sulphur vapours within the rock, in a natural steam bath maintained at between 38 °C and 42 °C with 95% humidity. The Thermes present it as the only natural hammam of its kind in Europe.

Medical Indications

The operator lists treatment for rheumatology (joint and rheumatic conditions) and for ENT and respiratory conditions (affections of the ENT sphere and the bronchi), alongside programmes for sports recovery and circulatory complaints such as heavy legs.

Facilities and Wellness

Alongside the medical cure areas, the spa offers a wellness and aquatic relaxation space with three thermal pools, including a rooftop pool, plus sauna, hammam, jacuzzi and sensory showers, and fitness and cardio-training areas. There is a spa using Sothys Paris products, and an on-site restaurant, Ilixo – Restaurant des Thermes de Luchon.

Treatments and Stays

Options range from the 18-day conventional thermal cure to shorter "Cure Liberté" stays of 3 to 5 days, morning discovery sessions and à la carte treatments.
