Hot springs in Hévíz

The lake water is a unique biological mix of sulfur, calcium, magnesium, and mild radon minerals, constantly replenished by deep subterranean cave springs that completely refresh the lake every seventy-two hours. The facility is the largest swimmable natural thermal lake on earth, featuring a central timber bathhouse from which swimmers float out among blooming pink water lilies. It suits couples and wellness travelers looking for a unique open-air natural environment. Because the lake is exceptionally deep, renting or bringing a foam pool noodle is highly recommended for effortless floating. Children under twelve are restricted from the therapeutic water due to its powerful mineral composition.
