Hévíz: the world's largest thermal lake

Fed by a natural thermal spring, Lake Hévíz remains the world's largest naturally heated bathing lake, warm year-round.

The center can be comfortably visited on foot, just steps away from the world's largest naturally heated lake.

The Thermal Lake of Hévíz, fed by a spring that completely renews the water every twenty-eight hours, maintains a swimmable temperature even in the depths of winter.

A short walk away, the wooden bathhouse pavilion from 1795, still in use, remains one of Central Europe's best-preserved historic thermal buildings.

Continuing toward the center, you visit the Church of the Holy Spirit, a Baroque religious building in the heart of the thermal town.

As evening arrives, the parks around the lake offer relaxing walks among tropical water lilies floating on the thermal surface.

Lake Hévíz renews completely every twenty-eight hours thanks to an underground thermal spring that gushes at over thirty-eight degrees, allowing bathing even in the harshest winters, with steam visible on the icy surface.

The waters of Hévíz, rich in sulfur and minerals, have been used for healing purposes since the eighteenth century, when the noble Festetics family built the first bathing facilities on the lake, laying the foundations of Hungarian thermal tourism.
