Curative Arshan springs, which were found by local hunters in 1960-s are popular all over Siberia. Carbonaceous silicon mineral water in the spring is unique all over the world. It has a wide range of temperatures: from cold (11-13 °С) to hot (+45 °С). The water type is similar to Vichi and Karlovykh Var (by silicon content), but unlike hot waters of these springs - Arshan originally is cold carbonaceous silicon mineral water. There are a lot of colorful stripes - zaala, which are tight to branches of near-by trees. The water in the spring has curative qualities and is used to heal cold, locomotive system problems. The mineral water is caught by borehalls (985 m3/day)and is being transfered by pipeline to drinking pump rooms and bath building.
