National Park
Đerdap National Park
Home to the Iron Gates gorge, where the Danube narrows dramatically between Serbia and Romania, with hiking trails and Roman-era ruins along its banks.
Founder, from Ruma, Serbia
Đerdap National Park stretches along the Danube where the river forces its way through the Carpathian mountains, creating the Iron Gates, the longest river gorge in Europe at around 100 kilometres. Romania lies on the far bank, and at the narrowest point, the Kazan gorge, the Danube squeezes to around 150 metres wide.
The park is packed with history. Golubac Fortress guards the entrance to the gorge, Trajan's Plaque marks the road the Romans cut into the cliffs, and Lepenski Vir is one of the most important Mesolithic sites in Europe. Hikers head for viewpoints like Veliki Štrbac and Ploče above the Kazan gorge, while boat tours cruise through the narrows.
Donji Milanovac is the main base, about three hours from Belgrade. The EuroVelo 6 cycle route runs along the river, so it's easy to combine cycling with hiking and boat trips. April to October is the season, and autumn colour in the forests is a highlight. Coming in spring? Time it with the Belgrade Marathon.
When to go
April through October, with spring and autumn offering the most comfortable hiking and cycling conditions.
Getting there
Roughly 2.5-3 hours from Belgrade by car, along the Danube's Serbian bank.

Đerdap questions
How much time should I plan for Đerdap?
A full day to 2 days. It is about 3 hours from Belgrade, so an overnight stay makes it more relaxed.
Are there Roman ruins here?
Yes, including Trajan's Plaque, a Roman inscription carved into the cliffside marking the ancient road built along the gorge.
Where should I base myself for Đerdap?
Donji Milanovac. It sits on the Danube in the middle of the park, close to the gorge and the boat trips.
How much does it cost to visit Đerdap?
Driving the river road and hiking are free. Golubac Fortress costs around €7.50 and a boat trip through the narrows around €25, paid on site. A guided day from Belgrade with pickup, fortress entry and the Iron Gates cruise included starts around €100. Check what's included before booking, as some cheaper tours charge the boat and fortress extra.
What are the Iron Gates?
The gorge where the Danube forces its way through the Carpathians, around 100 kilometres long and the longest river gorge in Europe. At the Kazan narrows it squeezes to roughly 150 metres wide.
Is Đerdap worth visiting?
Yes. The Iron Gates is the longest river gorge in Europe, and the combination of dramatic narrows, a Roman inscription cut into the cliffs and a major prehistoric site is hard to match.
What is Lepenski Vir?
One of the most important Mesolithic sites in Europe, a settlement on the Danube bank dating back thousands of years, now housed in a museum inside the park.
Can I hike or cycle here?
Yes. Marked trails climb to viewpoints like Veliki Štrbac and Ploče above the Kazan gorge, and the EuroVelo 6 cycle route follows the river through the park.
Ready to explore Đerdap?
Full day from Belgrade with pickup: Golubac Fortress, then a 70-minute boat cruise through the Iron Gates gorge. Fortress entry and the boat are included.
