Southwest France is home to the largest concentration of thermal spa towns in the country. From the Pyrenees to the Landes and Gers regions, 32 officially recognized thermal establishments draw on waters whose therapeutic properties have been known since Antiquity, supported by a long-standing tradition of medical thermal treatments. Each year, more than 200,000 spa guests and medical curists travel here for health and wellness stays.
This guide is the most comprehensive resource to help you choose a thermal cure or a short thermal spa escape. We explored the region to identify the places that truly matter — those where time slows down, where treatments follow ancestral practices, and where the natural setting alone is enough to restore balance. Discover our Wellness hub: curated spas, thermal baths and practical tips to plan your cure or getaway.
