If you arrive by train and keep to the main tourist area of Sibiu (Old Town, Strada Nicolae Balcescu and Piata Unirii), it is unlikely that you will ever need to use the city’s public transport system. The only bus routes of any interest are the Nos. 5 - which links the Gara (station) with Piata Unirii; 11 - Piata Unirii to the airport and 13 - Gara to Muzeul Satului (Astra Village Museum). Also of note is the No. 22, which serves Paltinis from the station, and 23 from the station to Rasinari.
Tickets (1.50 lei) for Sibiu’s buses must be bought from a kiosk or vending machine before boarding, and stamped in the little machines once on board. There is a fine of 50 lei if you are caught with no ticket.
Taxis are cheap in Sibiu and perhaps better than buses for longer distances. Just make sure you take a taxi belonging to a trusted taxi company, with the numbers 942 or 953 on the side. To call a taxi, dial (0269) 942 or (0269) 953.
