Les Bains de Saint-Thomas

In the Têt river valley of the Pyrénées-Orientales, in the commune of Fontpédrouse, the Bains de Saint-Thomas draw on six natural sulphurous hot springs that reach a striking 58°C, classifying the site as hyperthermal and placing it among the hottest natural water sources anywhere in the Pyrenees. The baths sit alongside the RN116, the historic road running parallel to the Têt and to the narrow-gauge Train Jaune (Yellow Train) line that climbs toward Cerdagne. A renovation in 1993 revived the site after a period of decline, and it has since become an important draw for the rural economy of this small mountain commune, popular with both cure-seekers and travellers on the Train Jaune route.
