Kuldur Hot Springs

Kuldur Hot Springs in the Jewish Autonomous Oblast of Birobidjan, 200 kilometres east of Khabarovsk in Russia's Far East, is a Soviet-era thermal sanatorium set deep in the taiga of the Bureya mountain range — one of the most remote and scenically pristine thermal resorts in Russia. The siliceous mineral waters, which emerge at temperatures of 38–55°C from ancient geological faults, are enjoyed in a long tradition of thermal bathing, and the sanatorium established here in the 1930s once served as a major rest and recreation facility for the Soviet Far East. The surrounding primary taiga forest, with its Siberian tigers, Amur leopards, brown bears and spectacular migratory bird populations, represents one of the world's most biodiverse temperate forest ecosystems. Kuldur offers thermal bathing in a genuinely wilderness setting, far from any urban influence, in one of the last great wild forests of the Russian Far East.
