Héviz, a small town only 6 kilometers from the western end of Lake Balaton, has a lake of its own... but what a lake! With an area of nearly 11 acres, it is Europe's largest warm-water lake. The surface temperature almost never falls below 30 C (86 F) even in midwinter.
In summer it feels like tepid bathwater; lilies thrive along the shore, as do oodles of baby fish. Health-seekers crowding the grass around the lake between dips make it look like a therapeutic Black pool or Coney Island.
