Water profile
Relaxing — deep, immediate muscle release.
Loaded with major ions — the essential minerals (Ca, Mg).
Dense, salty water — you float without effort.
In 1831, a fisherman stumbled upon a hot spring on the banks of the Rhône in Valais, and a geologist soon confirmed its existence. A first proper thermal establishment was built in 1836, complete with a cure building and a resident physician overseeing early prescriptions.
Lavey's water emerges at 65°C after an underground journey estimated at nearly 8,000 years, making it the hottest spring in Switzerland. Having descended through layers of limestone and granite, it gathers minerals along the way before rising back up through geological faults into today's pools, feeding a full thermal complex tucked into the Rhône valley.
