Lake Heviz is Europe’s largest thermal lake and the second largest thermal lake in the world. It is located in Hungary, about 8 km away from Keszthely.
The water of this lake is rich in carbonic acid, sulphur, calcium, magnesium, hydrogen carbonate and radioactive substances, which is believed to have medicinal properties.
The center of the lake is occupied by a wooden bath house, which was built in the 18th century and looks almost like it was more than two hundred years ago. Also, the entire lake is dotted with beautiful water lilies, which were brought to Hungary at the end of the 19th century.
Lake Heviz is fed by cold and warm water rich in mineral content that comes from the springs located in a 40 m deep cave. Its temperature varies between 23-25 °C in winter and 33-36 °C in summer.
Health industry is highly developed here due to the lake’s curative effect.
