Terme Čatež

Terme Čatež sits where the Krka River meets the Sava, in the Posavje region of southeastern Slovenia, on a thermal water field considered one of the largest of its kind in Europe. Eleven developed springs feed the resort, with source temperatures reported across a wide range of roughly 41–62°C and a combined flow around 125 liters per second — an unusually large output that lets the complex run one of the country's biggest outdoor and indoor pool networks year-round. The water carries a weak natural radioactivity noted in Slovenian balneological references. Spa-style tourism here dates to 1925, when the first hotel with 23 rooms was built beside a private bathing area; the resort has since grown into what is widely described as Slovenia's largest natural spa destination.
