We took tickets for a bus tour around Tbilisi at a special tourist stall (I found the address in Yandex). There are two types of buses with a heart and a flower. They have different routes. We had an audio guide. We offered an additional walk along the Kura River, which turned out to be 75 GEL per person. I really liked it. The route through Tbilisi, the main places of interest, an escort on buses who speaks Russian and other languages. You can drive until 21h on a purchased ticket, get off at stops, walk, then come back to this stop and wait for the bus. Buses pass by the bus stop every 30 minutes. They gave me a map with a route, two bottles of water. They also give small bottles of wine to everyone, but they didn't give us, because they bought a ticket with a boat together, like a discount one. Buses with a train, the top is open. The audio guide works great, everything is clear in Russian. The attendants additionally tell you where to get out better and what to see. I really liked it, I recommend it. While we were driving, we found a profitable exchanger, went out and exchanged rubles for lari. It's cool on the boat too, office chairs and sofas 👍 Aliko, a cool guy, drove us, told us everything, joked, speaks Russian. I recommend taking a walk.
