A thermal lake where swimming is possible even in the middle of winter—surrounded by steam, water lilies, and healing waters. This unique European phenomenon attracts millions of visitors every year.
When people say Hévíz is a spa town in Hungary, that description barely scratches the surface. In a country home to around 1,500 thermal springs and more than 270 types of mineral and medicinal waters, spa towns are nothing unusual. But Hévíz stands apart for one extraordinary reason: it lies next to the largest natural, biologically active thermal lake in the world, where swimming is possible all year round.
Hévíz Lake is a true natural wonder of Europe. It is thermal, biologically active, and medicinal, covering an area of more than four hectares. Thanks to powerful underground springs, the entire volume of water in the lake is naturally renewed approximately every 72 hours, ensuring constant freshness and purity.
Imagine a fairytale-like scene: you floating in warm water while snow gently settles on your hair, pink and purple water lilies drifting around you, and thick steam rising from the lake’s surface. It’s a moment made for unforgettable photos—and an experience unlike anywhere else in the world.
The water temperature remains pleasant throughout the year. In summer, it reaches 33–36°C, while in winter it never drops below 23°C, meaning the swimming season among the lilies truly never ends.

Healing Waters and Over 200 Years of Tradition
Hévíz is not just about relaxation—it is also renowned for its powerful healing properties. Traditional treatments here date back more than 200 years and have been confirmed by numerous medical studies.
The lake’s water has a unique composition, fed by two different thermal springs and enriched by medicinal mud covering the lakebed. Rich in minerals such as calcium, magnesium, and sulfur, the water is used for a wide range of purposes: from basic prevention and wellness to medical spa tourism and post-surgery rehabilitation.
While bathing, the warm temperature improves blood circulation, minerals are absorbed through the skin, and inhaling the rising thermal gases—especially in winter—may also have anti-inflammatory effects.
The healing thermal water is not limited to the lake itself. Many surrounding hotels offer access to it through pools, along with saunas, massages, and professionally guided therapeutic programs.
For all these reasons, Hévíz is often referred to as the “health and wellness capital of Europe.” It comes as no surprise that this small town is one of the most developed and visited tourist destinations in the region.
Although parts of the Hévíz Lake bathing complex are currently undergoing renovation, the thermal pools and the lake itself remain open to visitors—offering uninterrupted relaxation and enjoyment in one of Europe’s most extraordinary natural settings.
