After a day of hiking or skiing in Valais, there’s nothing quite like naturally hot water to soothe your legs. The canton has a special connection to thermal springs: some have been in use since Roman times, and the Leukerbad region remains one of Europe’s largest thermal spa centers today. In this guide, I’ll take you on a tour of the best wellness destinations in Valais, whether they’re large thermal centers open to the public or mountain hotel spas that you can visit without staying overnight.
Leukerbad: The Spa Capital of Valais
Leukerbad (Loèche-les-Bains in French) is undoubtedly the canton’s premier spa destination. The village, nestled at an altitude of 1,400 meters at the foot of the Gemmi, produces more than 3.9 million liters of natural thermal water every day, at a temperature ranging from 28 to 51 degrees depending on the source. This mineral-rich water supplies several facilities open to the public year-round.
The most iconic is a vast open-air thermal center with several outdoor and indoor pools, some of which offer a direct view of the Gemmi’s rocky cliffs—a truly spectacular setting for swimming in the middle of winter, surrounded by snow, with steam rising from the hot water. Another facility in the village focuses more on sauna areas and spa treatments, with an offering geared more toward pure relaxation than family swimming. I recommend checking the hours and peak times before heading there: on winter weekends, especially during school breaks, the pools can get very crowded.
The Recognized Benefits of Valais Waters
The thermal waters of Leukerbad are rich in calcium, sulfates, and magnesium. They’re traditionally used to relieve joint pain, rheumatism, and the aftereffects of intense muscle strain—making them an almost logical stop after several days of high-altitude hiking or skiing. Several studies conducted in Switzerland on thermal balneotherapy confirm a beneficial effect on muscle recovery and joint mobility, particularly among people suffering from osteoarthritis or chronic back strain.
Beyond the physical aspect, I find that the experience itself has something special about it: bathing outdoors in 36-degree water, surrounded by snow-capped peaks, provides a sense of relaxation that no urban spa can truly replicate. This is also why Valais’s thermal spas attract as many Swiss visitors as they do foreign tourists who come specifically for this experience.
Mountain Spas Open to the Public
Beyond Leukerbad, several mountain hotels in Valais have developed high-quality spa facilities, often accessible for the day via a day pass, without needing to book a room. This is an option I particularly appreciate for visitors passing through Zermatt, Saas-Fee, or Verbier who want a wellness break without having to make the round trip to Leukerbad.
These high-altitude spas generally offer a standard set of amenities: a heated indoor pool, a sauna area (Finnish sauna, hammam, steam room), a relaxation area with mountain views, and a menu of treatments and massages available by appointment. Rates and access vary from one establishment to another—I always recommend contacting the hotel directly to find out about its day-spa access policies, hours, and availability, which change depending on the season and occupancy rates.
After-Ski Rituals: A Deeply Rooted Tradition
In the Valais resorts, a wellness break at the end of a day of skiing is almost part of the ritual. You ski until the slopes close, then head straight to a relaxation area to unwind before dinner. This custom, which is very common in Verbier, Zermatt, and Crans-Montana, explains why most of the major resorts in Valais have developed a wide range of spa options, often with several competing establishments within a radius of a few hundred meters.

Wellness and Hiking: A Winning Combination
In my opinion, the most effective combination is still hiking in the morning and visiting the thermal baths in the afternoon. Legs that feel heavy after a climb to 2,500 meters recover remarkably well in water at 34–36 degrees. Leukerbad is also an excellent starting point for several high-altitude hiking trails, particularly toward the Gemmi, allowing you to combine hiking and thermal relaxation without leaving the valley. To help you plan your outings, I’ve detailed the best hiking routes in Valais in my guide to hiking in Valais.
Practical Tips for Planning Your Visit
- Reservations: During peak season (winter break, July–August), I recommend booking your time slot in advance at the major thermal centers, as crowds may limit access during peak hours.
- What to bring: a swimsuit, a towel (sometimes available for rent on-site), pool sandals, and a swim cap if you’re using the indoor pools.
- Duration of a visit: Allow at least two to three hours to fully enjoy a thermal spa with multiple pools and a sauna circuit.
- Best time to visit: winter, for the unique experience of swimming outdoors in the snow; late summer afternoons, after a hike, to watch the sunset over the mountain peaks from the outdoor pools.
- Access: Leuk-les-Bains is accessible by car or local bus from the Leuk (Leuk) train station on the main Valais line.
A Region to Explore in Its Entirety
Wellness is just one of the many facets of Valais. For a broader view of the canton, its valleys, and its villages, I recommend my general guide to Valais. And if you’re planning a trip to the Saas-Fee area—whose valley offers beautiful places to relax in addition to its glaciers—I’ve compiled useful information in my guide to Saas-Fee. To round things out, my article on the Swiss Valais as a health destination takes a broader look at the region’s recognized therapeutic benefits, beyond just thermal spas.
My final tip
Don’t save your only moment of relaxation for the end of your stay: in Valais, a midweek spa break often allows you to head back out hiking or skiing with refreshed legs the following days. This is a region where wellness isn’t just a tourist add-on, but a genuine local tradition, rooted in the canton’s geology and Alpine culture for centuries.
