France's hot springs are thermes, and at least 36 of them sit in this directory, built around a long cure-thermale tradition. The grand spa town of Thermes de Vichy anchors the volcanic Auvergne, while Les Thermes Dax in the southwest is one of the country's busiest thermal centres. 35 of the 36 listed here are paid spa centres. Developed thermalisme, not wild soaks, defines the country.
The Pyrenees along the Spanish border hold the densest run of mountain thermes in France. The spa baths of Thermes de Cauterets and Thermes de Luchon (Ressources & Vous) sit in high valleys, Bagneres-de-Bigorre Thermal Spa serves the Bagneres area, and the one free pool in the country, Sources Chaudes de Merens-les-Vals, steams wild near Ax-les-Thermes. A dozen of the directory's French springs line this southern mountain chain.
The Auvergne and Massif Central, built on extinct volcanoes, hold the most famous French spa towns. Thermes de Vichy VY Resort drew an imperial court in the nineteenth century, while Le Mont-Dore Thermal Spa and the very hot waters of Chaudes-Aigues Thermal Centre (Par Aqui), which emerge far hotter than most French springs, sit nearby. Several of the listed French springs cluster across this central volcanic region.
The Alps and Savoie gather lake and mountain spas in the east. The lakeside cure centre of Thermes d'Aix-les-Bains Chevalley and the ski-town baths of Thermes de Saint-Gervais Mont-Blanc and Brides-les-Bains Thermal Spa pair thermal water with mountain settings, while Evian Thermal Spa sits above Lake Geneva. Many of the springs listed here lie across these eastern mountains.
The lowlands, the Vosges, and the north round out the map with historic cure towns. The spa resort of Les Thermes Dax in the southwest treats more curists than anywhere else in France, while Vittel Thermal Spa and Plombières-les-Bains (Calodae Spa) serve the Vosges and Enghien-les-Bains Thermal Centre sits near Paris. These lower-lying thermes complete the directory's French entries.
French thermal bathing centres on thermalisme, a medical cure tradition where doctors prescribe multi-week treatments at spa towns. Most sites are developed cure centres and day spas rather than wild springs, which sets France apart from countries with free backcountry pools. 35 of the 36 springs listed in this directory charge entry, with one free Pyrenean pool. Water is piped into baths and treatment rooms at the larger towns. These sit within the wider hot springs in Europe.
