Vertiginous route in the Bonnant gorges at Saint-Gervais, in three sections (D, D+, TD+). Equipped route for experienced climbers with waterfall views.
Unique thermal spa fed by thousand-year-old water naturally heated to 39°C, nestled in a 10-hectare wooded park in Le Fayet.

Nestled deep in a 10-hectare wooded thermal park in Le Fayet, the Saint-Gervais Mont-Blanc Thermal Baths invite you to a unique wellness experience. The thermal water, which fell on the peaks of the Mont-Blanc massif 6,500 years ago, springs naturally at 39°C after a long underground journey through the Alpine rocks. Drawn from 101.5 meters depth, it is recognized by the French Academy of Medicine for its soothing, healing and anti-inflammatory properties.
The Mont Blanc Thermal Baths Spa (approximately 2,000 m²) offers a holistic two-level circuit. On the ground floor, the mineral universe evokes the water's journey between the Earth's depths and magma, with experience corridors (ice and mist), floating pools and immersive alcoves. Upstairs, the circuit is dedicated to mountain sensations: alpine garden, refuge sauna, halotherapy cave, outdoor open-air pools at the foot of the Bonnant Gorge. Each workshop—visual, auditory, sensory—celebrates the poetry of this ancient water.
Beyond the spa open to all, the establishment offers accredited thermal treatments (dermatology, respiratory tract, ENT) and innovative programs: post-cancer treatment, long covid, tinnitus. A treatment institute, a boutique of thermal water-based cosmetics, and massage and ritual offerings complete the experience. Whether you seek relaxation, skin regeneration or joint relief, the Saint-Gervais Thermal Baths are a unique haven in Haute-Savoie, combining thermal expertise with an exceptional natural setting.
