On the road between Alkhatsikhe and Vardzia, the small hamlet of Tsunda has a family-run mineral bathhouse where naturally hot spring water fills an indoor pool. The water is clear and warm — not scalding — and has a slightly sulphurous mineral quality typical of the region's geothermal springs. After a day of walking at Vardzia or in the surrounding hills, it is one of the most restorative stops in southern Georgia.
The setup is genuinely rustic: a concrete building with a pool fed directly from the spring, two showers, and the kind of welcome that makes you stay longer than planned. The family charges a flat rate for the bathhouse. If you ask nicely, they may let you join them for dinner. The experience is not polished, which is entirely the point.
