Tbilisi literally means “warm place”, and the brick domes of Abanotubani are why: hot sulfur water has been piped into these bathhouses since the city began. Book a private room, submit to the kisa scrub, and emerge an hour later with the softest skin of your adult life and a mild sense of having been laundered.
Evenings and weekends book out; reserve a room a day ahead or bathe mid-morning. An hour is enough for a first visit, and the scrub is worth its small supplement every time.
The quarter sits at the foot of Narikala in the Old Town, beside the Leghvtakhevi waterfall gorge. Cable car down, bathe, then dinner in the lanes: the classic Tbilisi evening.
