Stretch of waters in Germany

Rivers

The six biggest rivers of Germany are Rhine, Elbe, Weser, Ems, Oder and Donau. The first four of them flow into the North sea, the Oder flows through the East sea into the Atlantic ocean and the Donau flows into the Black sea.
The Rhein is 865 kilometres long and is one of the busiest waterways in Europe.
The Donaus is 674 kilometres long and it's most important inflows are Iller, Lech, Isar und Inn.


Sea

Germany doesn't have mant coasts, it only borders on the East Sea and on the North Sea.
Both are rather cold seas - usually the water makes less than 20 degrees in the summer, even if the sun is shining and it is really hot. So if you're looking for hot beach - holidays, you better go to italy or for example greece.
