Danube
Europe's second-longest river
The Danube is Europe's second-longest river, flowing roughly 1,800 miles from Germany's Black Forest through central and southeastern Europe to the Black Sea.
It passes through or borders ten countries, including Austria, Hungary, and Romania.
Vienna, Budapest, and Belgrade sit on its banks.
A cruise down the Danube is a classic European tour.
