Why go
Tskaltubo Cave lies beneath the same hills that drew Soviet elites to Georgia's most famous sanatorium town, where thermal radon baths healed party officials from 1950 to 1991. The cave's stable 14°C temperature and 100% humidity once served as natural therapy for respiratory ailments, extending the town's wellness mythology underground. Unlike show caves elsewhere, Tskaltubo remains raw and lightly visited, its flowstone curtains, stalactite forests, and rimstone pools forming slowly over millions of years in the karst of the Imereti plateau. The connection to Tskaltubo's UNESCO-recognized sanatorium architecture—now being revived—makes this a rare pairing of Soviet modernism and deep geologic time.
