Raduga, meaning rainbow in Russian, is a thermal resort in the Chundzha and Arasan area of Kazakhstan's Almaty Region, where radon-bearing mineral springs feed bathing facilities in a leisure complex serving the southeastern Kazakhstan wellness tourism corridor. The radon springs, gently radioactive and part of Central Asian balneology within a long thermal tradition, are offered alongside recreational pool facilities within a resort that caters to families and visitors from Almaty and the wider Ili River valley region. The Raduga complex is part of a cluster of thermal resorts that has made the Chundzha valley one of Kazakhstan's most developed mineral water tourism zones outside the capital.
