Canton Valais is not only the capital of après-ski; conquered by the Romans in 25 B.C.E., it’s also home to Switzerland’s largest concentration of ancient thermal baths, including popular spots like Brigerbad and Leukerbad. A lesser-known favorite is Les Bains de Saillon, a 45-minute drive from the Les 4 Vallées ski area (Switzerland’s largest), and home to a refurbished thermal-bath complex. There you can soak your muscles in bubbling waters while watching the pink Alpenglühen (Alpine glow) glide across the toothy summits. Its lengthy outdoor Rivière Thermale, aka lazy river, is lined with grottoes, steam rooms, and saunas, while physical and massage therapists remain at the ready indoors to help visitors recuperate from ski-related injuries—or simply to facilitate some indulgent pampering.
