The centre of Sofia is easily accessible by public transport, which includes trams, buses and trolleybuses. Buses run from 5am until midnight and trams run until 1am. Single-trip tickets can be purchased before boarding as well as on the vehicle.Renting a car is impractical, given the volume of traffic and limited number of parking spaces in and around Sofia. Taxis are cheap and easily available, though. Tariffs are usually shown on the vehicle window. If they're not and there's no meter, passengers should negotiate a fare before setting off. Many tourist attractions are set close together, making Sofia a walkable city for sightseers.For the most part, safety isn't a worry. Visitors should be aware of their possessions at all times, though, as pickpockets operate in some popular tourist areas.
