About Sofia
Bulgaria's capital has quietly grown into one of Southeast Europe's more interesting city-break destinations - affordable, compact, and with a mix of Roman ruins, Orthodox churches, and a lively craft-beer and café scene. Vitosha mountain rises directly south of Sofia, offering hiking and skiing effectively within the city limits.
