Soothing — neither hot nor cold, perfect balance.
Rich in active gases or metals — a strong mineral character.
Soft water — natural, classic buoyancy.
Chaudfontaine in the Vesdre valley near Liège is the only natural thermal spring in Belgium, where sulphurous water at a constant 36.6°C — the temperature of the human body — emerges from the Carboniferous limestone aquifer in a remarkably gentle and body-temperature-perfect mineral spring that has been used therapeutically since Roman times. The spring's extraordinary property of emerging at exactly human body temperature has made it a uniquely accessible thermal water, requiring no cooling before bathing and creating a particularly gentle and enveloping soaking experience. The elegant neoclassical Casino spa complex and the Parc des Sources on the wooded Vesdre riverbank preserve the 18th and 19th-century spa tradition that made Chaudfontaine the exclusive destination of Liège's wealthy elite.
