Sofia: Why It Is Worth the Trip

Bulgaria’s capital, Sofia, is a hidden gem with budget-friendly appeal. Don’t miss the stunning Alexander Nevsky Cathedral, a symbol of the city with its gold-domed roof and intricate mosaics. Entrance is free, making it perfect for travelers snagging those cheap flights. Wander through the nearby markets to sample local banitsa (a flaky pastry) or hike Vitosha Mountain—just a short trip from the city center. With its mix of Roman ruins, Ottoman baths, and vibrant nightlife, Sofia delivers big experiences for small budgets.
