Long considered the kind of provincial town you race through en route to the Serbian border, Danube-hugging ILOK is fast emerging as one of eastern Croatia’s most compelling destinations. With wine cellars galore grouped around an imposing hilltop castle, it certainly promises enough to keep you occupied for a day or two. The town can also boast a great choice of affordable accommodation, making it a far better base for exploring the region than Vukovar. With the bridge to the Serbian side of the Danube only 2km downstream, it is also a good jumping-off point for Novi Sad and Belgrade.
