Belgrade: Serbia’s capital on the Danube and Sava

• Kalemegdan is at the confluence of the Sava and Danube; Knez Mihailova links the fortress with Republic Square in the city centre.
• The Nikola Tesla Museum is in Vračar, at 51 Krunska Street; guided tours start every hour and last around 45 minutes.
• Zemun is a distinct historic district on the Danube; Vračar and the riverside districts are outside the central walking route.
• In 2025/26, the fast train to Novi Sad serves Petrovaradin station, with a bus connection into the city.

Kalemegdan brings together fortress walls, gates, green spaces and viewpoints overlooking the Sava and Danube. From the park, the pedestrian street Knez Mihailova leads to Republic Square; cafés, shops and historic façades line the way. This central walk links the fortress, the city centre and striking river views without requiring a detour to another district.

The city centre and Novi Sad offer different perspectives on Serbia. Novi Sad combines the Danube with Petrovaradin and a more compact old town; Belgrade has greater distances and a variety of districts.

The Nikola Tesla Museum is in Vračar, at 51 Krunska Street. Visits take the form of a guided tour covering Tesla’s life, personal belongings and working models of his machines. As of 24 October 2026, the museum schedule lists opening hours of 10 am to 6 pm on Mondays and 10 am to 8 pm Tuesday through Sunday; tours start every hour and last about 45 minutes. Groups of 11 or more need a reservation; individual visitors do not.

With Gardoš and the Danube waterfront, Zemun makes for a separate city walk west of the centre. Skadarlija offers a different focus, with restaurants and streets in the old quarter. Public transport connects these areas with the centre.

For a more relaxing stay in Serbia, spa towns and health resorts complement a city-focused trip. To broaden your travel comparisons to other European river landscapes, consider the Danube Bend and the Balkans.

For travel within Serbia, the railway connects Beograd Centar and Petrovaradin. According to the published timetable for 14 December 2025 to 12 December 2026, the Soko runs to Petrovaradin; from there, a bus connection takes you to Novi Sad. A seat reservation is required for Soko trains. Novi Sad can therefore be added to a visit to the capital as a separate stop.

A longer trip around Europe can also include Hungary, Croatia, Romania and Slovakia as separate destinations. For your stay in Belgrade, plan how to get back between districts with getting there and getting around. When planning your trip, consider the location of your accommodation and return routes; entry requirements and documents and staying safe while travelling are also part of organising your stay.

Staying near Kalemegdan and Knez Mihailova means shorter trips to the fortress and city centre. The Tesla Museum is in Vračar, while staying in Zemun puts you by the Danube waterfront. When choosing accommodation by location and type of trip, consider the district where you’ll spend most of your time. Kalemegdan and the museums bring together culture and history.

For Eastern European itineraries, you can also combine Serbia, Novi Sad and more of Eastern Europe. Depending on your plans, two to three days in Belgrade is enough to get a good first impression. You can organise your visit around museums, the rivers and different districts.
