Your wellness break at altitude
Imagine stepping out of a steaming hot Jacuzzi, it's snowing, you're in your bathing suit but you're hot, and in front of you, the mountains.
No, it's not a dream after too much mulled wine. It's just a normal day at the Grands Bains du Monêtier.

Roman trilogy
the hot-cold course
The principle is simple: you alternate between three pools at different temperatures, just as the Romans did 2,000 years ago (and they had it right).
Start with the Caldarium (38-42°C): hot water that turns you into clay. Your muscles relax, your brain switches off and you go limp. That's what it's all about.
Follow with the Tepidarium (28-34°C): the transition phase when your body says "oh yeah, okay, let's slow down". Not too hot, not too cold, just enough to keep you zen.
Finish with the Frigidarium (15-20°C): this is where it stings. But it's this cold water that wakes you up, activates your circulation and makes you feel invincible afterwards. Three minutes is all it takes, I promise.
Hammam
and Sauna discovery
HAMMAM, a moment of relaxation... Steam detox
38-42C° of humid heat that draws out all your toxins. You enter, you sweat, you leave with a brand-new skin.
How does it work? The steam does all the work. Your muscles relax, your skin breathes, and mentally, you're elsewhere. Stay for 10-15 minutes max per session, then go outside for some fresh air, and repeat if you like.
Pro tip: a cold shower afterwards = baby-smooth skin guaranteed.
SAUNA DÉCOUVERTE - a gentle initiation
The sauna is dry heat (between 3 and 20% humidity) that makes your body sweat and activates your parasympathetic nervous system. Translation: it really relaxes you.
The proven effects? Stress reduction, improved sleep quality, relief from skin problems (psoriasis, acne), and boosted blood circulation.
The "discovery" version goes up to 58-62°C instead of the classic 80-90°C.
It's enough to feel all the benefits, but accessible even if it's your first time. You stay as long as you like (usually 10-15 minutes), and get out when your body tells you to.
And much more ...
AMPHORUS BASIN
26-30°C. The preparation pool to gently wake up your muscles before activities or hot baths. Spend a few minutes here and you're ready for what's next.
MUSICAL GROTTO
You lie down in the warm water (35-40°C), submerge your ears, and... music literally vibrates through your skull. It's weird to explain, but ultra-relaxing to experience.
The sound travels through the water and resonates throughout your body. Add light effects, and you're off into a kind of aquatic trance. Close your eyes, let go and let yourself be carried away. Literally.
MINERAL BASIN
Water between 35 and 40°C enriched with mineral salts and trace elements. Translation: your skin absorbs the good stuff while the hydromassage jets take care of your muscles.
It's like a massage, but you're in hot water. The jets are strong, so position yourself strategically to target your lower back, shoulders, calves... in short, anything that's been getting a bit sore on the slopes.
WARM MARBLES - NAP TIME ALLOWED
Heated marble slabs where you lie down after your baths. The heat spreads gently down your back, your muscles melt and you go into sleep mode.
It activates your blood circulation, drains the water accumulated in your legs, and above all, turns you into an ultra-relaxed soft pancake. Many people fall asleep. It's normal, that's what it's all about.
OUTDOOR POOL - THE LEGENDARY SPOT
34-40°C outdoors, whether it's snowing or -10°C outside. This is THE pool for which Les Grands Bains is famous.
You're in the warm water, the snow is falling on your head (or the stars are shining if you come at night), and in front of you: the mountains. The open-air Jacuzzi and aquabeds (submerged deckchairs) are packed, and it's easy to see why.
There's a counter-current course for those who want to get moving, powerful jets to massacre your burnt-out shoulders, and a solarium in summer for sunbathing after the bath. But let's be honest: nobody comes here to work out. We come to bask in the warm water facing the peaks.
Tip: Come at night. Outdoor pool + starry night = moment of life.
