Sofia is a city where Roman ruins sit beside Ottoman mosques, Orthodox cathedrals and stern Soviet blocks, often on the same street. The gold-domed Alexander Nevsky is the obvious landmark, but the real character is in the leafy yellow-brick avenues, the mineral springs where locals fill bottles, and the cafés below Vitosha mountain. September brings warm days and cool evenings, ideal for wandering before hiking the trails just outside town.
