Trains, buses, trolleys and trams as well as famous Kharkov metro (subway) help to save on getting around and see all must sees. For sure it will give you an insight into daily life of Kharkovites and see the real country, maybe make new acquaintances as its always a good idea to ask for directions people passing by if you got lost.
