Romanian cities generally have very good public transport systems comprised of buses, trams, trolleybuses and, in some cases, maxitaxis. Bucharest is the only Romanian city with an underground metro. The method for accessing the systems is broadly similar. Purchase bus or tram tickets at newsagents or street kiosks marked bilete or casă de bilete before boarding, and validate the ticket once aboard. For maxitaxis, you usually buy a ticket directly from the driver. Tickets generally cost from 2 to 3 lei per ride.
