Make the most of our thermal spa
Chaudfontaine is a thermal hot spring with a storied past. It’s a miracle of nature, thanks to the exceptional conditions in its sub-soil. Nature provides the spring with a unique level of protection and ensures the constant quality of its mineral water. The practically impenetrable rocky soil, and the limestone layers of the Ardennes, purify the water on a constant basis, adding essential elements in the process.
During a journey that lasts more than 60 years, this water flows to a depth of 1,600 metres. The water reaches a temperature of 55° in the earth and is then pushed back towards the surface via the pressure. It emerges in Chaudfontaine as natural mineral water at a temperature of 37°.
