The Danube Gorges – Iron Gates Natural Park

The Carpathian Mountains in the north (on the Romanian side) and the Balkan Mountains in the south (on the Serbian side) form the Iron Gates, a canyon where the Danube meets the Black Sea. The best place to see the keys is in the village of Dubova, where visitors can enjoy spectacular views of the Danube flowing through the narrow canyon after a 30-minute walk.

Small cruises through the gorge can be started from nearby ports, where visitors can admire stone-carved inscriptions from the Roman period or visit a few caves that are directly accessible from the Danube.
