The city blends Ottoman, Soviet, and modern European influences, best explored through its bustling markets and cozy mehanas (taverns). With your cheap flights savings, treat yourself to a day trip to Vitosha Mountain—just a short bus ride from the city center. Explore Bulgaria beyond Sofia, and you'll find thermal springs, ancient ruins, and the breathtaking Rila Monastery.
