1 dollar, which is less than 3 GEL, gives you the opportunity to travel by bus or metro 5 times and even be left with some change. One-way fare on the municipal transport is as little as half a GEL (50 Tetri). Moreover, if you use a debit card for transportation called “Metromoney”, you can travel for free (as many times as you want) over the period of 90 minutes after the first trip. Another way of transportation is using microbuses (Marshutka) in Tbilisi – costing only 0.80 GEL (around 0.25 $). Even if you decide to take a taxi, it will not cost you much, because usually “an average” trip in Tbilisi is only 5 GEL. If you decide to go from one outskirt to another, a driver might ask for the maximum amount of 20-30 GEL.
Bear in mind the most important rule: Never ever pay more than 25 GEL for a taxi from the airport to Tbilisi center! Taxi drivers might ask several times more when they hear your foreign language. Bargain, or get another taxi. There are plenty. You could also download an app Taxify. Drivers are rated here and the price is calculated according to the distance. It is not expensive and you are always confident in the quality service.
A journey from town-to-town is not expensive either. One of the most popular route is Tbilisi-Batumi (requiring 5 hours). Traveling by comfortable bus, offered by Metro-Georgia will cost you 25 GEL. Moving by train, the same route is 46 GEL (17 $) for First-Class, and just 20 GEL for Economy-class.
