Đerdap National Park
The Iron Gates gorge, where the Danube narrows between cliffs, watched over by a rock-carved face and a Roman inscription.

At the Iron Gates the Danube squeezes between the Carpathian and Balkan ranges into a gorge over a hundred kilometres long, narrowing at points to a few hundred metres with cliffs rising directly from the water. It is the largest gorge in Europe by several measures. Carved into the rock on the Romanian bank is Decebalus, an enormous modern face of the Dacian king cut in the 1990s and 2000s, facing the Roman Tabula Traiana on the Serbian side across the water. The park was set up in 1974 over some 63,800 hectares, and in 2020 the wider area became Serbia's first UNESCO Global Geopark. Golubac fortress guards the western entrance with towers stepping up a spur, restored and open to climb. At Lepenski Vir, an archaeological shelter holds a Mesolithic settlement whose sandstone sculptures of fish-like faces are among the oldest monumental art in Europe.
The landscape
- Golubac Fortress - restored medieval towers at the gorge's western gate.
- Lepenski Vir - a Mesolithic settlement with fish-faced sandstone sculptures, under cover.
- Decebalus rock face - the giant carved head above the water, seen from a boat.
- Boat trips through the narrows - the gorge from the water, where the cliffs are highest.
When to go
May to October. Autumn colour on the gorge slopes is excellent and the light is best in the morning on the Serbian side. Boat trips depend on weather and demand, and run less often outside summer.
Good to know
The Decebalus carving is on the Romanian bank and is best seen from a boat, which needs arranging; from the Serbian road it is distant. Lepenski Vir is a shelter over an excavated site rather than a large museum, and the sculptures are small. Distances along the gorge road are long and there are few places to stop for food.
Nearby
Felix Romuliana lies south; Belgrade is around three hours west.
