Insider tip — Sovata is home to Lacul Ursu (Bear Lake), a heliothermal salt lake in the Transylvanian hills whose upper layers absorb solar heat to reach exceptional temperatures in summer, while the hypersaline lower layers act as thermal insulators. The dense salt water provides extraordinary buoyancy and the lake's gynecological and rheumatological treatments have drawn visitors since the 19th century. The surrounding fir forests and the cluster of smaller salt lakes make Sovata one of Romania's most distinctive spa destinations.
