Vukovar-The footpath along the Danube in Vukovar is the closest to the beautiful Danube. If you want to get to know the Danube by sight, smell and feel, this is the greatest place to do it. In the center of the town, next to the 'Dunav' hotel and the port for tourist boats, the promenade also leads to the spot where the Vuka river empties into the Danube.
