Crime rates in Belgrade are relatively low, but it's wise to stay vigilant against petty theft, especially in crowded areas. Avoid walking alone at night in poorly lit locations, particularly in the neighborhoods of Borča and municipally near the River Sava. Familiarize yourself with local customs and etiquette; for instance, it's customary to greet with a handshake. Always keep your belongings secure and consider using a money belt or crossbody bag.
