The old town and Rustaveli Avenue are compact enough to walk. Most visitors spend much of their time within the area bounded by Freedom Square, the old town, Abanotubani, and the Bridge of Peace — all of this is walkable.
Metro: Two intersecting lines cover the main arteries. The stations are Soviet-era (deep platforms, escalators, functional). A single journey costs 1 GEL; buy a Metromoney card at any station. The metro runs 6am–midnight.
Taxis and ride-hailing: Bolt, Yandex Go, and other apps operate in Tbilisi and are cheap — a ride across the city centre costs 5–10 GEL. Metered taxis at fixed ranks (notably at the airport and Freedom Square) are reliable. Flag-down street taxis are less regulated; agree on a price before getting in.
Buses and minibuses: An extensive network of buses and minibuses covers the wider city and suburbs. They are cheap but the routes are hard to decipher without the local knowledge. The metro is easier for most tourist destinations.
Cable car: The cable car from Rike Park to Narikala Fortress is the most scenic way to reach the fortress ridge. It runs most of the day and costs 2.5 GEL each way.
