Kungur Ice Cave is a karst cave located in the Urals, near the town Kungur in Perm Krai, Russia, on the banks of the Sylva River. With a length of explored passages over 5 km, it is one of Russia’s biggest karst caves and the only one in the country equipped for visits by tourists. Over thousands of years rainwater dissolved the soft rocks and formed a system of spacious underground halls, filled with rocks of peculiar shapes.
