Zalakaros Thermal Hotel Karos Spa

Zalakaros Thermal Hotel Karos Spa is a luxury thermal hotel at Zalakaros in Zala County, southwestern Hungary, where one of Hungary's most powerful thermal spring systems was discovered during oil exploration drilling in 1962 at a depth of 2,300 meters, yielding water at 96 degrees Celsius loaded with iodine, sodium, and organic minerals that have made Zalakaros one of the most important spring destinations in the Hungarian thermal tradition since its rapid development into a major spa resort from the 1970s onward. The spring water's exceptional iodine concentration and organic mineral content have earned Zalakaros a place among the country's most distinguished thermal destinations within a long tradition of bathing associated with well-being. The gentle southwestern Transdanubian landscape of Zala County, with its vineyards, oak forests, and the proximity of Lake Balaton — Central Europe's largest freshwater lake and Hungary's premier leisure destination — situates Karos Spa in a richly attractive natural and cultural setting for one of Hungary's finest thermal hotel complexes.
