Trams, trolleybuses and buses cover the whole of the city, including the outskirts. Tickets must be bought from kiosks prior to boarding and validated on the bus or tram. Look for the punching devices on the wall of the bus, insert the ticket and punch. Many trams and trolleybuses now have ticket machines at the front, where you can buy a ticket that does not need punching. The ticket is only valid for the journey on that particular tram/bus; if you change - you will need to punch a new ticket. One ticket costs 1 lev (0.5 Euro).
