Catch glimpses of surprise "settlements" along the routes, and prepare to be awed by the authenticity of the tracks, switches, depot, and switch lights. After the ride, you can check out the display area with many railroad artifacts.

The Royal Palace was built between 1924 and 1929, on orders by King Alexander I, as the official royal residence. It is designed in the Serbian-Byzantine style, surrounded by pergolas, park terraces, pools, a pavilion, and a concert terrace. Located on the ridge of a hill, it provides a magnificent view of Dedinje, the Košutnjak forest, Topčider, and Avala. Within the same complex, a residence for sons of King Alexander I had been built and named the White Palace. Its salons are arranged in the styles of Louis XV and Louis XVI, and it contains a valuable art collection including notable artworks by Rembrandt, Fromentin, Vouet, Poussin, Bourdou, Jakšić, Meštrović and many others. It also contains the Royal Library that once housed around 35,000 books and the Ceremonial Dining Hall set up in the Chippendale style. The palace complex also contains the Royal Family Church modelled after the Church of the Monastery of St Andrew on Treska in Macedonia. Palaces are open for visits on weekends, during the tourist season, as it is a home of His Royal Highness Crown Prince Alexander of Serbia and his family.

Once a separate city, Zemun is now a renowned part of Belgrade, famous for its river taverns, unique atmosphere, and small restaurants specialising in fresh fish from the Danube. The main street of Zemun is home to the Homeland Museum and the Madlenianum Opera and Theatre. Along the Danube, Zemunski kej is a kilometre-long promenade featuring barge-cafés, an amusement park. The former largest hotel in Belgrade, Hotel Jugoslavija, now hosts the Grand Casino. At night, the barge-cafés become the epicentre of nightlife, staying open until dawn. Gardoš Tower, also known as Millennium Tower, stands as Zemun's most iconic symbol, offering panoramic views of Belgrade and a tranquil escape from urban noise. The neighbourhood has retained its authentic charm, with narrow, mostly cobbled streets and individual residential houses.
