Belgrade

60-hectare fortress on the headland where the Sava meets the Danube — Roman, Byzantine, Ottoman, and Habsburg walls layered together. Leashed dogs welcome on all open ramparts; the famous sunset viewpoint is dog-friendly.

Bohemian quarter — a single 400-metre cobbled street lined with traditional Serbian kafane taverns, live music, and 19th-century townhouses. Leashed dogs welcome the entire length; nearly all terraces accept pets.

800-hectare artificial peninsula on the Sava, nicknamed 'Belgrade's sea', with a marked dog beach on the eastern end open year-round. Forest, lakes, and summer beer gardens; bus 53/56 from the centre.

Belgrade's pedestrian spine, 1 km from Trg Republike to the Kalemegdan gates, lined with Belle Époque facades, embassies, bookstores, and dog-friendly café terraces.

9-hectare central park around St Mark's Church, with a fenced municipal dog park on the south side (opened in 2018). Mature plane trees, gravel paths, and several café-kiosks; three blocks east of Skadarlija.

One of the world's largest Orthodox churches, 79 m tall, dominating the city skyline. The interior admits only assistance dogs, but the wide square outside and the surrounding Vračar park are leash-friendly and free.
