The Danube is the second longest river in Europe, after the Volga. It forms the border to Serbia, and Bulgaria.
The Iron Gates is a gorge on the river, where road 57 sits along the shores providing a great scenery. It is smooth asphalt, and there are plenty of hotels, B&B’s, and restuarants on the route.
Not too far from the town of Orsova, is the statue of Decabulus (last King of the Dacian Kingdom), carved into the rocks.
