Les Bains du Val d’Illiez Thermal Baths — Closed Since 2019

Valais / Wallis · Updated 28 August 2026

The thermal baths at Les Bains du Val d’Illiez have been closed since 2019, and there is currently no confirmed reopening date. A local initiative is seeking to restore and reopen the Thermes Parc, potentially from 2027, but the project is not yet certain.

For visitors looking for thermal baths now, the best nearby alternative is the hot springs spa at Les Bains de Lavey.

Could the Val d’Illiez Thermal Baths Reopen?

The Thermes Parc Les Bains du Val-d’Illiez closed its doors to visitors in 2019. Recent satellite imagery shows the pools empty, while adjacent properties remain occupied and well maintained.

Attempts to reopen the baths have been made but have thus far been unsuccessful. A 2024 EHL study looked at redevelopment of the site, but the various proposals would require major renovations and tens of millions of francs of investment. Supporters have mentioned 2027 as a target, but substantial financing and redevelopment work would still be required.

There is currently no confirmed reopening date or even firm, approved redevelopment plans.

The following describes the facilities at Thermes Parc before the thermal baths closed in 2019. Prices, opening hours, transportation details, and services are historical and should not be used for planning a current visit.

The Thermes Parc Les Bains du Val-d’Illiez was a relaxing mineral hot water spa resort with warm baths, saunas, Jacuzzis, jet streams, steam baths, and day-spa treatments and massages. The spa baths were beautifully located in the Illiez Valley, an easy drive from the Rhone Valley, Lake Geneva, and several Portes du Soleil ski resorts in Switzerland and France. Several restaurants and an apartment hotel were available on premises — some are still functioning but now, of course, without the benefit of the adjacent thermal spa.

Les Bains du Val d’Illiez Thermal Park in Switzerland

The thermal baths of the Thermes Parc Val d’Illiez were a modern day spa with hot water baths and a regular range of massages, beauty and wellness treatments. The facilities were modern, but the concrete and steel constructions were mostly wood-clad in the beautiful traditional style of Illiez Valley architecture.

The thermal baths at the Val d’Illiez Thermes Parc were around 34°C and included a large covered bath in the main hall, a smaller outdoor pool linked by a river to the indoor area, and a large exterior bubble bath. All the main baths had a range of Jacuzzis, bubble beds, and massage jet streams. The sulphuric smell of the mineral waters was quite strong.

Further water features in the park were open during warmer weather.

The Iliez River flows through the park and this Alpine stream is of course very cold in comparison to the baths.

The sauna, tylarium, and hammam (steam bath) area was only open to adults.

Visiting Les Bains du Val d’Illiez Before It Closed

Before closing in 2019, the thermal baths operated year-round and offered timed admission to the pools, with separate wellness facilities. Children under four were not admitted.

The admission ticket was in the form of a small watch-like wristband, which also gave access to the lockers.

Restaurants and Hotels at the Bains du Val d’Illiez

Visitors were not allowed to bring food and drinks into the thermal baths area. A small snack bar could be accessed directly from the baths.

La Bergerie, a typical Swiss chalet-style restaurant, is adjacent to the thermal baths complex and seems to be still operating. It also has a wine bar and functions as a tearoom outside meal times.

The thermal park complex is surrounded by several large six-story chalets with apartments ranging from studios to 5-room flats. Many remain in use and available for vacation hire. These buildings are in the typical style of the valley with wooden balconies and overhanging roofs.

Transportation to the Val d’Illiez

Getting to Val d’Illiez remains easy by car or public transportation. The basic routes are unchanged, although the former brown “Les Bains” road signs have been removed.

Driving times to Val d’Illiez are from Geneva 1h20 (120 km), Lausanne 0h50 (60 km), Bern 1h30 (120 km), and 0h50 (60 km) from Sion.

By train, change in Aigle from the mainline in the Rhone Valley to the small mountain railway heading to Champéry. The mostly hourly train takes around 45 minutes from Aigle to Fayot, the small station right above the thermal baths. The train only stops at Fayot on request (sur demande) – press the button as on a city bus. (Fayot is the stop in between Val d’Illiez and Pont de Fayot.) See Swiss Railways for timetables and tickets.

Travel time by train to Fayot is around 2h20 from Geneva, 1h20 from Lausanne, and 2h30 from Bern.

The Val d’Illiez is low on formal sights, but visitors will enjoy the special traditional architecture, traditional Swiss villages and beautiful Alpine scenery. A visit to the valley also combines well with visiting the picturesque and historical Chateau d’Aigle with its winemaking museum.
