Free Sofia Tour
Typically led by a Bulgarian student or graduate, the English-language Free Sofia Tour gives a two-hour hit of the city's main attractions. The tour is Sofia's number-one activity on Tripadvisor and has the backing of the city municipality. On the back of its success, its founder has co-created the United Free Europe network, which also features similar tours in nine other European cities, including Lisbon, Prague and Berlin.
