About Tbilisi

May-September is the sweet spot: soak in Abanotubani, ride the cable car to Narikala, and taste wine bars. Mild months suit hillside climbs and open-air feasts.

Travel Tips

Baths & Old Town Timing
Sulfur baths book evening slots that sell out - reserve ahead. Narikala cable car is quieter mid-morning than sunset.
Metro & Marshrutkas
Metro covers main axes cheaply; marshrutkas reach outer districts. The old town and baths area are walkable but hilly.
Cable Car & Museum Fees
Narikala cable car and major museums charge modest fees. Wine tastings in town or Kakheti day trips are the bigger optional costs.
Hospitality & Hills
Georgian hospitality can mean abundant toasts - pace yourself. Wear grippy shoes for steep old-town lanes and sulphur bath floors.
