Geography and Course of the Danube River

The Danube River originates in the Black Forest region of southwestern Germany, near the town of Donaueschingen, where two small rivers, the Brigach and the Breg, merge to form the nascent Danube. From there, the river embarks on an extraordinary journey spanning approximately 2,850 kilometers (about 1,770 miles), making it the second-longest river in Europe after the Volga. Along its course, the Danube passes through or borders ten countries: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine, before finally emptying into the Black Sea via the Danube Delta.

Within Austria, the Danube traverses a stretch of roughly 350 kilometers, flowing eastward through the northern part of the country. It courses through key Austrian cities such as Linz, the capital of Upper Austria, and Vienna, the nation’s capital and largest city. The river’s path in Austria is a defining feature of the landscape, cutting through the scenic Wachau Valley—a UNESCO World Heritage site known for its vineyards, historic towns, and cultural landmarks. The Danube’s broad floodplain and terraces have also influenced settlement patterns, agriculture, and infrastructure development throughout Austrian history.

One notable geographical feature along the Austrian Danube is the Iron Gate, a dramatic gorge marking the river’s passage from the Carpathian Mountains into the Pannonian Plain, though the Iron Gate itself is primarily located downstream in Serbia and Romania. In Austria, the river’s elevation drops gradually, creating a navigable waterway that has been harnessed for commerce and travel since ancient times.
