Soft water — natural, classic buoyancy.
Vulkaneifeltherme in Bad Bertrich, Rhineland-Palatinate, is Germany's only natural glauberite (sodium sulfate) thermal spa — a unique mineralogical distinction that makes its sulfated waters exceptionally rare in the European balneological landscape, drawing on springs formed by volcanic activity in the Eifel volcanic field, one of Central Europe's most recently active volcanic regions. The Eifel's volcanic heritage, which includes maar lakes, volcanic cones, and CO₂-rich mineral springs (Heilwasser), created Bad Bertrich's distinctive sulfated thermal waters, prescribed since the Roman period for digestive and hepatic conditions. The Vulkaneifeltherme's combination of a genuinely unusual mineral profile, the volcanic scenery of the Eifel landscape, and a small, historically charming spa town setting makes Bad Bertrich one of Germany's most mineralogically distinctive thermal destinations.
