Lake Hévíz
Lake Hévíz – A Natural Thermal Lake Near Lake Balaton
Just a short drive from Lake Balaton, Lake Hévíz offers one of Hungary’s most distinctive wellness experiences: bathing outdoors in a naturally warm thermal lake. Surrounded by greenery and fed by mineral-rich thermal springs, the lake can be enjoyed throughout the year, with water temperatures remaining pleasantly warm even in winter. Whether you come to unwind in the thermal water or simply experience an extraordinary natural setting, Hévíz makes an easy wellness escape during a Lake Balaton stay.
Why Lake Hévíz is Special
Lake Hévíz is the world’s largest biologically active natural thermal lake. Its mineral-rich water rises from a spring cave around 38 metres below the surface, with an exceptionally strong natural flow that replaces the lake’s water roughly every three days. The water remains warm throughout the year – staying above 22°C even in winter and reaching around 35–38°C in summer. Surrounded by a protected forest, the lake feels remarkably different from a conventional thermal bath: here, the spa experience takes place in a living natural environment. Find out more
What to Expect When You Visit
Bathing in Lake Hévíz is unlike visiting a typical indoor thermal spa. Most visitors float or swim slowly in the warm open-air water, surrounded by water lilies and the forested shores of the lake. Swimming rings are commonly used for relaxing on the water, while changing facilities and wellness services are available within the Lake Bath complex. The experience changes with the seasons, but bathing outdoors in naturally warm water – even on a cool or misty day – is part of what makes Hévíz so memorable.
Good to Know Before You Go
Lake Hévíz is open for bathing, but some parts of the Lake Bath are currently operating differently than usual. Bathing in the thermal lake is available outdoors, while the central bath building (“A” building and “B” terrace) remains closed. Other facilities, including the Festetics Day Spa, wellness area and covered relaxation spaces, remain accessible. As opening hours, available areas and seasonal facilities may change, it is worth checking the latest information before your visit. Find out more
