Situated in north-east Serbia on the border with Romania, the site covers a section of the River Danube gorge and adjacent belt of land, about 6 km in width and some 100 km in length. This is a transboundary IBA shared with Romanian site 032 `Porþile de Fier reservoir'. Human activities include boat traffic on the Danube.
The site is important for breeding raptors and wintering waterbirds, holding 20,000 or more individuals on a regular basis during winter (45,000 in January 1999). This is also believed to be an important area for migrating storks and raptors but further data on numbers are needed. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (wintering), Aquila heliaca (passage) and Crex crex (3-7 breeding pairs).
