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.

Ada Ciganlija, Belgrade's most renowned summer resort, has transformed from an island to a peninsula, becoming the city's largest and most picturesque recreational spot. The Savsko lake is encircled by over 7 km of Blue Flag-awarded beaches, offering myriad ways to enjoy hot summer days. In summer, Ada Ciganlija turns into a bustling hub, attracting over 100,000 visitors daily (up to 300,000 on weekends) for swimming, sports, or leisurely afternoons in beachside cafés. In contrast, autumn and winter bring a quieter atmosphere, with a scenic promenade lined by cafés and nightclubs, although the lake's ice is too thin for skating. With more than 50 open-air sports facilities, including a golf course and cable-ski circuit, as well as courts and pitches for various sports and extreme activities like bungee-jumping and paintball, there's no shortage of action. The area's restaurants offer traditional city fare, particularly fish specialities, while bars and floating river clubs provide vibrant nightlife.

The oldest stable of the island, Provo Ponies offers both group and private horseback riding tours through Long Bay Beach. You'll be able to wade through the waters with the provided steed; trotting and cantering will be available, if conditions allow it, on the two rides that are scheduled every day.

In 1928, the famous artist Ivan Meštrović designed a sculpture for the drinking fountain on Terazije. The public was against having a nude male figure set up in the city centre, however. After World War I, the project was cancelled and thus the Victor was set up on Kalemegdan instead. The plato next to the monument is among the most crowded places in the city, where visitors love to take photos and enjoy the view over New Belgrade and Zemun.
