Chreli Abano at 14 Abano Street in the historic Abanotubani district offers the most authentic sulfur bath experience in Tbilisi. Private rooms cost 100-150 gel ($37-56) for one hour depending on size and amenities, open 8am-2am daily. I'll be honest — I was completely intimidated my first time, having no idea what to expect from this centuries-old Georgian tradition.

Book by phone (+995 32 272 1040) or simply walk in, though early morning visits between 8-10am guarantee better room selection and a more peaceful experience. Bring your own swimsuit and towel, or rent towels on-site for an additional 10 gel. The staff will show you to your private dome-shaped room with a small pool of naturally heated sulfur water.

The mineral-rich water maintains a constant 37-40°C and locals swear by its healing properties for skin conditions and joint pain. What struck me most was the historical connection — Tbilisi was literally founded around these hot springs in the 5th century, and soaking here feels like participating in something deeply rooted in Georgian culture. Coming from Paris where everything feels rushed, this has become my favorite way to decompress after long days exploring the cobblestone streets.

Budget alternative: Abano #5 at 1 Shulaveri Street for 70 gel, though the facilities show their age and lack the charm of Chreli's meticulously maintained domed chambers.
