Germany is a country rich in natural beauty. Between the North Sea and Baltic coasts in the north and the peaks of the Alps in the south lie extremely diverse landscapes, with everything from wide expanses of river and lakeland scenery, hilly uplands and densely wooded regions to agricultural plains and industrial conurbations. The Zugspitze is the highest mountain in Germany at 2,963 metres. Germany's longest river is the Rhine, which flows through the country for a total of 865 kilometres. Germany has 14 national parks, 101 nature reserves and 15 biosphere reserves.
