Why go
Nunisi Springs is a modest Soviet-era sanatorium turned quiet wellness retreat, tucked into the mixed forests below Borjomi-Kharagauli National Park. Its hydrogen-sulphide springs, discovered in the 19th century and developed scientifically under Soviet rule, draw locals seeking relief for skin and joint conditions. The outdoor concrete pools—simple, unadorned, fed directly from the source—let you soak in mineral-rich water between 34–38°C while surrounded by oak and hornbeam. There is no luxury here, only function: the sulfur's faint egg scent, the green canopy overhead, the slow rhythm of Georgian families who have returned annually for generations. It is worth the journey for the rare authenticity—an unpretentious, working spa where the treatment is the landscape itself.
