Novi Sad

Serbia

Best for: Architecture, Nightlife, Riverside, Festivals, Chill, Budget Friendly

Novi Sad, Serbia — a relaxed Danube city crowned by the Habsburg-era Petrovaradin Fortress, known equally for its pastel old town and as the summer home of the EXIT music festival.

Petrovaradin Fortress's clocktower and tunnels are free to explore and give the best river views in the city. The pedestrian old town around Zmaj Jovina street is dense with cafés, while Štrand beach on the Danube is where locals cool off in summer.
