Abanotubani sits at the southern edge of Tbilisi’s old town, tucked into a gorge where the Mtkvari River bends and the city stops trying to look like itself. The domed rooftops of the bathhouses - round, brick-coloured, and perforated with skylights - rise just above street level, which makes the whole district feel like it’s partially underground, or at least not quite committed to being above it. The sulfur smell hits before you see anything.

This is the right kind of introduction. Tbilisi’s hottest neighbourhoods for travellers tend to cluster around Rustaveli Avenue or the cable car end of the old town, where the light is good and the cafés are dense. Abanotubani draws far fewer tourists not because it lacks atmosphere, but because it demands something from you first: a slight tolerance for the smell, and the willingness to actually use the baths rather than photograph them.

The bathhouses here have operated for centuries - the city’s name is said to derive from the Georgian word for warm, tbili, because of these very springs. Most of the baths offer private rooms that can be rented by the hour, usually for a small group. The experience is not a spa in any modern sense. The water is genuinely hot, the rooms are stone and steam, and the kisi scrub - offered by an attendant if you want it - is as aggressive as it sounds. It’s not a performance of wellness. It is, more precisely, the kind of bathing that exists because it works.

The district around the baths is worth the extra time. Metekhi Church stands on the cliff above, and the old Persian-style wooden balconies of the surrounding streets are in various states of beautiful disrepair. Some houses look like they’re held together by the vines growing over them.

The best practical move is to book a private bath room in the morning, when the heat is easier to manage and the lanes around Abanotubani are still quiet. By early afternoon the tour groups arrive, though they tend to stay at street level, taking pictures of the domes without going in.

Whether that counts as their loss probably depends on how you feel about sulfur water and being scrubbed by a stranger. Some people find it immediately obvious that it should be on every Tbilisi itinerary. Others leave unsure - and that uncertainty feels more honest than the usual consensus.
