Đerdap National Park stretches along the right bank of the Danube River from the Golubac Fortress to the dam near Novi Sip, Serbia. It was established in 1974 and spreads on 63,786.5 ha. The park management office is in the town of Donji Milanovac on the Danube. Across the river is the Parcul Natural Porțile de Fier in Romania. In July 2020 the wider area of the national park was designated as the UNESCO global geopark, as the first protected area from Serbia labeled that way.
