VUKOVAR, CROATIA – NOVI SAD, SERBIA. Vukovar is a Croatian symbol of resistance, which you’ll better understand on your city tour showcasing the Ovčara Memorial and Eltz Manor House. Alternatively, choose a wine tasting in Ilok, a center of wine production since Roman times, where you’ll sample its famous Grasevina, Traminac and Frankovka wines. Back on board, cruise to Novi Sad, sometimes called the “Serbian Athens.” Discover Novi Sad on a walking tour to Dunavski Park and through Stari Grad, the Old Town center. During the evening, visit Petrovaradin Fortress, a mighty stronghold no enemy has ever breached. (B,L,D)
