Lake Hévíz

About

Lake Hévíz is located in Hévíz, Hungary, near the western end of Lake Balaton, 8 kilometres (5 mi) from Keszthely. Hévíz means 'hot water'. It is the largest swimmable European thermal lake, with its waters originating from two springs in a 38 m (125 ft) deep cave. The flow of water is very strong and the water in the lake is completely replenished every three and a half days. The springs are the last in a south-west line of karst waters stretching along the Transdanubian Mountains.
