Your Wellness Getaway at High Altitude
Imagine this: you step out of the steaming hot tub, wearing just your swimsuit but feeling warm, with the mountains stretching out before you.
Practical information in one click:
ROMAN Trilogy
The Hot-Cold Journey
The concept is simple: you alternate between three pools at different temperatures, just as the Romans did 2,000 years ago (and they really knew what they were doing).
Start with the Caldarium (38–42°C): the hot water turns you into putty. Your muscles relax, your mind unwinds, and you become limp. That’s the point.
Move on to the Tepidarium (28–34°C): the transition phase where your body says, “Oh yeah, okay, let’s slow down.” Not too hot, not too cold—just right for staying zen.
Finish with the Frigidarium (15–20°C): this one stings. But it’s this cold water that wakes everything up, gets your circulation going, and leaves you feeling invincible afterward. Three minutes is all it takes—I promise.
Hammam
and Open-Air Sauna
HAMMAM, a moment of relaxation... Detox through steam
38–42°C of humid heat that draws out all the toxins. You step in, you sweat, and you step out with skin that feels brand-new.
How does it work? The hot steam does all the work. Your muscles relax, your skin breathes, and mentally, you’re transported to another place. Stay for 10–15 minutes max per session, step outside for some fresh air, and repeat if you’d like.
Pro tip: Take a cold shower afterward—baby-soft skin guaranteed.
OUTDOOR SAUNA —A Gentle Introduction
A sauna involves dry heat (between 3 and 20% humidity) that makes your body sweat and activates your parasympathetic nervous system. Translation: it really relaxes you.
Proven benefits? Reduced stress, improved sleep quality, relief from skin conditions (psoriasis, acne), and a boost to blood circulation.
The “introductory” version reaches 58–62°C instead of the usual 80–90°C.
That’s enough to feel all the benefits, but it’s still manageable even if it’s your first time. You can stay as long as you like (usually 10–15 minutes); just step out when your body tells you to.
And much more...
AMPHORA POOL
26–30°C. The warm-up pool to gently awaken your muscles before activities or hot baths. Spend a few minutes here, and you’ll be ready for what’s next.
MUSICAL CAVE
You lie down in the warm water (35–40°C), submerge your ears, and then... the music literally vibrates through your skull. It’s hard to explain, but incredibly relaxing to experience.
The sound travels through the water and resonates throughout your entire body. Add some light effects, and you’re swept away into a sort of aquatic trance. Close your eyes, let go, and let yourself drift. Literally.
MINERAL POOL
Water between 35 and 40°C enriched with mineral salts and trace elements. Translation: your skin soaks up all the good stuff while the hydromassage jets work on your muscles.
It’s like a massage, but you’re in warm water. The jets are powerful—position yourself strategically to target your lower back, shoulders, calves… in short, everything that’s taken a beating on the slopes.
HEATED MARBLE SLABs—NAP TIME ALLOWED
Heated marble slabs where you can lie down after your bath. The heat gently spreads through your back, your muscles melt away, and you drift into a state of relaxation.
It boosts your blood circulation, drains the fluid buildup in your legs, and, best of all, turns you into a super-relaxed, limp pancake. Lots of people fall asleep. That’s normal—it’s meant to happen.
OUTDOOR POOL - THE LEGENDARY SPOT
34-40°C en extérieur, peu importe qu'il neige ou qu'il fasse -10°C dehors. C'est LE bassin qui fait la réputation des Grands Bains.
Vous êtes dans l'eau chaude, la neige tombe sur votre tête (ou les étoiles brillent si vous venez en nocturne), et devant vous : les montagnes. Le jacuzzi en plein air et les aquabeds (transats immergés) sont pris d'assaut, et on comprend pourquoi.
Il y a un parcours à contre-courant pour ceux qui veulent bouger, des jets puissants pour massacrer vos épaules cramées, et un solarium l'été pour bronzer après le bain. Mais soyons honnêtes : personne ne vient ici pour faire du sport. On vient pour se prélasser dans l'eau chaude face aux sommets.
Le bon plan : Venez en nocturne. Bassin extérieur + nuit étoilée = moment de vie.
NEW: Spa La Rotonde, a sanctuary entirely dedicated to wellness
Since February 2026, the Grands Bains has expanded beyond the ground floor. Upstairs, an entire space has been transformed to create Spa La Rotonde: a unique retreat, designed as a true haven of calm, reserved for guests 16 and older.
Here, the pace changes completely. Gone is the lively, family-friendly atmosphere of the Grands Bains; in its place is an immersive sensory experience, bathed in natural light and offering views of the Alpine peaks.
What awaits you at La Rotonde:
- The sensory immersion pool, the spa’s centerpiece: a 12-meter-long panoramic screen displays images and atmospheres for total immersion as you float.
- The sparkling water pool, featuring micro-bubble stimulation technology that provides an immediate sensation of lightness.
- The natural waterfall, at around 42°C, fed directly by the Monêtier hot spring, known since Roman times.
- The snow room, between 2 and 5°C, for an invigorating contrast after the hammam.
- The salt room, lined with Himalayan salt walls, for the benefits of halotherapy.
- The panoramic sauna and the enveloping hammam, with views of the mountain peaks.
- The outdoor hot tubs on the terraces.
The wellness tea room, to extend your relaxation with delicate flavors.
Practical information to keep in mind:
Access restricted to guests 16 and older; capacity limited to 50 people.
Admission: 3 hours = €55 / 4 hours = €65.
Access and reservations are separate from those for the Grands Bains: reservations are required and can only be made online, directly on the Spa La Rotonde page.
Open on the same days and at the same times as the Grands Bains.
