Public Transport
You will probably find the center of Sofia more accessible by tram, bus, or trolley bus than by car due to the shortage of parking space. Public transport runs from 5am till midnight for buses, metro and trolley buses and till 1am for trams. Tickets are for single trip and are sold at kiosks at the major stops, at newsstands or in driver's cabin. You have to punch them inside the vehicle. If you transfer you must use another. Tickets are inspected at random by conductor.
