Water profile
Soothing — neither hot nor cold, perfect balance.
Loaded with major ions — the essential minerals (Ca, Mg).
Soft water — natural, classic buoyancy.
The Thermes Grandjean at Avène-les-Bains, in the limestone gorges of the Hérault department, are intimately linked to the international reputation of Avène thermal water for the treatment of sensitive, atopic, and psoriatic skin conditions—a dermatological tradition endorsed by generations of French dermatologists and clinically studied since the early 20th century. The Avène spring's water is remarkably soft, low in minerals, and slightly siliceous with anti-irritant properties that distinguish it from most European thermal waters, making this an internationally recognized destination for severe skin disorder treatment. Surrounded by the garrigue scrubland and dramatic limestone cliffs of the upper Orb Valley, the spa offers both medical seriousness and the wild natural beauty of southern Languedoc.
