Belgrade may be one of the most underrated destinations in Europe. Even Rick Steves, who covers most of former Yugoslavia, doesn’t have a guidebook for Serbia, and bloggers seem to only praise Belgrade for its nightlife. While we don’t frequent bars and clubs, we thoroughly enjoyed our three nights in this capital city just exploring different areas on foot, like Belgrade Fortress, Ada Ciganlija (a man-made lake) and Knez Mihailova (a pedestrian shopping street). It also helped that we were introduced to two wonderful new friends, Mileva and Nikola, who, like Justin, are dentists (which, as a profession, we learned is strikingly different than in America). Now we have visited all four capital cities on the Danube River: Vienna, Bratislava, Budapest and Belgrade!
