Sofia is amply covered by an interlocking network of trams, buses and trolleybuses, with services running from about 05:00 to 23:30. Despite some new additions to the fleet, however, vehicles tend to be antiquated, filthy, overcrowded and above all slow: it can take half a lifetime to cross the city from one side to the other. An additional problem is posed by the lack of information concerning routes – while bus and tram stops in the city centre are marked with numbers of services and details (in Cyrillic) of destinations served, those in the suburbs are invariably rusty old shacks bearing no information whatsoever. Your only hope is to buy a decent city map with tram and bus lines marked on it – then study it for as many months as it takes to learn them all by heart.

Several popular cross-town routes are operated by privately owned minibuses (marshrutki). Rather than being limited to specific stops, they can be hailed at any point along their route, and will drop passengers off on request. There aren’t any tickets: simply jump in, press yourself into an available corner, and pass 1.50Lv forward towards the driver. Many people prefer marshrutki to regular buses because of their speed and convenience; others are turned off by the tendency of drivers to pack passengers in like sardines and then career around the city like crazed drag racers. If you're in any way prone to travel sickness, don't forget to take a puke bag.

A single metro line runs from Serdika station in the city centre to the western suburb of Lyulin – which is great if you happen to live in Lyulin, but not much use otherwise. If you fancy a ride just for the heck of it, tickets (0.70Lv) are different from those used in trams and buses, and can only be purchased from ticket counters in the underground stations themselves.
