Discover the Thermal Spa!

Nestled at the bottom of the Thermal Park, Les Thermes de Saint-Gervais invites you to enjoy an unforgettable relaxing moment !

The Mont Blanc Thermal Baths Spa offers a half-day of relaxation in an exceptional setting. A wellness course in thousand-year-old, naturally-hot and beneficial thermal water. Relaxation workshops, saunas at different temperatures, steam baths, a herbal tea room and, of course, indoor open baths at the foot of the Bonnant Gorge.  Each workshop transcribes new experiences: visual, auditory and sensory. Les Bains du Mont Blanc takes a holistic approach to well-being that puts a spotlight on the poetry of the journey of Saint-Gervais Mont Blanc thermal water

The ground floor spaces are inspired by the water’s journey from the depths of the Earth, caressing the rocks on it’s way and drawing as close as possible to the earth’s magma.


A spectacular setting that appeals to all the senses. Upstairs, the course is dedicated to the sensations of the water, once it has surfaced from the ground.


It focusses on the water throughout the seasons, how the lights and sounds interact, how they combine and carry you with them. The bottom of the gorge has been developed to make way for a tree-lined landscape punctuated by pools of thermal water right in the heart of nature.







A HYDROTHERAPY concept designed for you


Dive into the history of our thermal water, Les Bains du Mont Blanc begins in a very dark atmosphere, where the thermal water draws its heat after a long trip from the peaks of alpine glaciers to the bowels of the earth. From there, you will enter the birthplace of the thermal water. A place where time stands still. Embark on a path of discovery where you will travel between peaks and underground before springing up into the light in the heart of the Bonnant Gorge.

Les Bains du Mont Blanc becomes a holistic place where the body and the mind are connected. 

The backdrop between the sky and the Earth on the ground floor reveals the thermal water’s best kept secrets. Each square metre is designed for you to enjoy the water in all its phases. Walking through the spaces is a true multisensory journey: experience corridors where you can discover the ice water and the heat mist, immersive alcoves, floatation, observation and stimulation pools. Outside, four outdoor four open air pools at various temperatures can be found at the bottom of the gorge.


The area is conducive to contemplation, whatever the weather and whatever the season. The first floor is dedicated to the sensations of a walk in the mountains: a halotherapy cave, alpine garden, alpine refuge sauna, seasonal alcoves and, for sustenance, a beautiful contemplative space opens out overlooking the mountain.
