Balatonfüred on the northern shore of Lake Balaton has been Hungary's most celebrated resort town since the 18th century, when its carbon dioxide-rich medicinal springs became famous for treating heart and circulatory conditions. The Balatonfüred Thermal Spa and Heart Hospital tradition continues to this day: the local springs, which bubble up at 11°C but are heated for bathing, contain sodium-calcium-magnesium-hydrogen carbonate and free carbon dioxide with documented cardiovascular benefits. The main public bathing complex near the lakeshore offers thermal pools, a swimming pool, saunas, and treatment facilities. The combination of thermal bathing, the beautiful Balaton lakeside setting, and the town's elegant 19th-century promenade makes Balatonfüred one of Hungary's most refined spa destinations.
