About the place
The lake of Hévíz is the biggest biologically active, natural medicinal water in the world. Its temperature is affected by the combination of cold and hot spring waters coming from underground. The medicinal water breaks out from the spring cave on the surface at the rate of approx. 410 litres per second and with a temperature of 40°C. According to that delivery, the water in the lake changes every three and a half days and keeps uniformly clean.
