Les Bains du Rocher

The naturally heated sulfur water here was particularly popular among 19th-century aristocrats who arrived in Cauterets to "take the cure." Today, it’s still used to alleviate rheumatism and respiratory maladies (three-week treatments can even be covered by national health insurance). In keeping with modern trends, however, the station thermale now caters to guests who simply want to relax. Les Bains du Rocher has a genuine spa aesthetic and offers massages, facials, aqua-gym sessions, and, of course, soaks in hot healing pools both inside and outside.
