Tourists are invited to attend the traditional grape harvest during the 44th annual show called "Ilocka Berba" ("Ilok Vintage" in an unofficial translation).
A majority of entertainment events will take part in the medieval town centre on 2-4 September.
Ilok is well-known for wines, Traminac (Gewurztraminer), Grasevina (Riesling) and some other sorts, as well as for the delicious local cuisine.
