Along its course the Danube also passes through 10 countries: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Romania, Moldova, and Ukraine.
The Rhine River is the river that rises in Switzerland and then flows northward to the North Sea.
The river that rises in Switzerland is the Rhine river.
The Rhine is one of the major European rivers.
The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Swiss-Liechtenstein, Swiss-Austrian, Swiss-German.
The river rises in the Aare Glacier of the Bernese Alps in Bern canton, below the Finsteraarhorn and west of the Grimsel Pass, in the south-central part of Switzerland.
As the Aare flows north past Meiringen, the river cuts through the scenic Aare Gorge.
Major European rivers also run through Switzerland: the course of the Rhine is 375km long, the Rhone more than 264km and the Inn 90km.
The Rhine flows into the North Sea, the Rhone into the Mediterranean, and the Inn into the Black Sea, via the Danube.
Central and Eastern Europe's largest river, the River Danube does not directly travel through Switzerland, but again has a key tributary in the country.
The Inn, which starts in the Engadine region of the Swiss Alps, flows from Switzerland through to Germany and Austria.
The Rhine is the longest river in Germany. It is here that the Rhine encounters some more of its main tributaries, such as the Neckar, the Main and, later, the Moselle, which contributes an average discharge of more than 300 m3/s (11,000 cu ft/s).
Flowing through six countries, the Rhine River has served as a link between southern and northern Europe since Roman times.
