Niska Banja is the old spa settlement just east of Nis, known for warm mineral springs and a broad view back across the Nisava valley. The setting is low-key rather than luxurious: a park, spa buildings, places to eat, and paths that make it an easy half-day break from the city.
The hot springs are traditionally used for rheumatic and heart conditions. Visitors who are not coming for treatment can still enjoy the park and use the area as a starting point for nearby gorges and monasteries.
