The town is being developed as a balneological center. There is a cold mineral water spring (18-26 C) with the flow rate of 120 liters per minute at the distance of 500 metres west of it. There is a balneo-sanatorium built up here. The mineral water treats some skin diseases, the nervous system, kidney related diseases and others. There is a nice park and a country-houses zone around it.
