Terme Čatež
Lower Sava Valley (Posavje), Čatež ob Savi
One of the largest natural thermal water areas in Europe, at the confluence of the Sava and Krka rivers, where 11 developed springs yield weakly radioactive bicarbonate water between roughly 41°C and 62°C at a combined flow of about 125 liters per second.
