At 1320 kilometers the Rhine is the longest river in Europe. It rises in the Swiss Alps issuing from the Rheinwaldhorn Glacier 3,353 m above sea level. It flows generally north, passing through or bordering on Switzerland, Liechtenstein, Austria, Germany, France, and the Netherlands before emptying into the North Sea at Rotterdam. Its important tributaries are the Aare, Neckar, Main, Moselle, and Ruhr rivers. Canals link the river with the Maas, RhÃ´ne-SaÃ´ne, Marne, and Danube (via the Main) valleys. The Rhine is connected to the Mediterranean Sea by the Rhine-Rhone canal and is joined to the Black Sea by the Rhine-Danube canals.
