Les Thermes de Saint-Gervais Mont Blanc

Les Thermes de Saint-Gervais Mont Blanc sits at the foot of the Mont Blanc massif, drawing on a natural thermal spring that emerges at 39°C after a journey through alpine rock lasting centuries. The water carries a mix of minerals and trace elements — sulfur, magnesium, boron, silicon, copper, manganese — and has a long-standing reputation in dermatology and burn care for its soothing, anti-inflammatory and skin-repairing properties.

The facility centers on a thermal pool with both indoor and outdoor sections, letting bathers move between covered areas and open-air baths with mountain views. A steam room, sauna and cold plunge round out the circuit for those cycling through hot-and-cold contrast bathing. Beyond the pools, the center runs a program of dermatological thermal cures and spa treatments built around the same water source, aimed at visitors dealing with skin conditions as well as those simply looking to unwind.

Access is by reservation, with day passes available alongside longer cure packages for people staying five to ten days or more. The baths welcome both adults and families, though specific sessions or zones may be restricted to adults only — worth confirming when booking. Opening hours shift through the week: the latest closing time is 9pm on Fridays and Saturdays, with earlier closes on Sunday (7pm) and Wednesday (7pm), and the site is closed on Tuesdays. Pricing falls into the moderate range for the region's thermal spa offerings.
