Aare

The fourth one in Top 9 Longest Rivers in Switzerland that Toplist would like to introduce to you is Aare. The Aare, also known as the Aar, is a tributary of the High Rhine and the longest river that originates and flows entirely within Switzerland.

Its total length from its headwaters to its confluence with the Rhine is approximately 295 kilometers (183 miles), during which time it descends 1,565 meters (5,135 feet), draining an area of 17,779 km2 (6,865 square miles), almost entirely within Switzerland, and accounting for nearly half of the country, including all of Central Switzerland.

Along the Aare, there are more than 40 hydroelectric plants.

The Aare rises in the Bernese Alps' great Aargletschers (Aare Glaciers), in the canton of Bern, west of the Grimsel Pass. The Finsteraargletscher and Lauteraargletscher join to form the Unteraargletscher (Lower Aar Glacier), which is the Grimselsee's main source of water (Lake of Grimsel). The Oberaargletscher (Upper Aar Glacier) feeds the Oberaarsee, which in turn feeds the Grimselsee. The Aare flows northwest through the Haslital, forming the magnificent Handegg Waterfall, 46 m (151 ft), past Guttannen, after leaving the Grimselsee just to the east to the Grimsel Hospiz, below the Grimsel Pass.
