The Aare (Swiss Standard German: [ˈaːrə] ) or Aar (Swiss Standard German: [aːr] ) is a tributary of the High Rhine and the longest river that both rises and ends entirely within Switzerland.[2][3]

Its total length from its source to its junction with the Rhine comprises about 295 kilometres (183 mi),[2][4] during which distance it descends 1,565 m (5,135 ft), draining an area of 17,779 km2 (6,865 sq mi), almost entirely within Switzerland, and accounting for close to half the area of the country, including all of Central Switzerland.[4]

There are more than 40

hydroelectric plants along the course of the Aare.[5]

The name was Latinized as Arula/Arola/Araris.[6][nb 1]

Inside the Aare Gorge

The Aare rises in the great

Haslital, forming on the way the magnificent Handegg Waterfall, 46 m (151 ft), past Guttannen
.

Right after Innertkirchen it is joined by its first major tributary, the Gamderwasser. Less than 1 kilometre (0.62 mi) later the river carves through a limestone ridge in the Aare Gorge (German: Aareschlucht).[2] It is here that the Aare proves itself to be more than just a river, as it attracts thousands of tourists annually to the causeways through the gorge.[3] A little past Meiringen, near Brienz, the river expands into Lake Brienz. Near the west end of the lake it indirectly receives its first important tributary, the Lütschine, by the Lake of Brienz. It then runs across the swampy plain of the Bödeli (Swiss German diminutive for ground) between Interlaken and Unterseen before flowing into Lake Thun.[2]

Near the west end of Lake Thun, the river indirectly receives the waters of the

Lac de Bienne. From the upper end of the lake, at Nidau, the river issues through the Nidau-Büren Canal, also called the Aare Canal,[3] and then runs east to Büren
. The lake absorbs huge amounts of eroded gravel and snowmelt that the river brings from the Alps, and the former swamps have become fruitful plains: they are known as the "vegetable garden of Switzerland".

From here the Aare flows northeast for a long distance, past the ambassador town Solothurn[2] (below which the Grosse Emme flows in on the right), Aarburg (where it is joined by the Wigger), Olten, Aarau,[2] near which is the junction with the Suhre, and Wildegg, where the Seetal Aabach falls in on the right. A short distance further, below Brugg, it receives first the Reuss, its major tributary, and shortly afterwards the Limmat, its second strongest tributary. It now turns due north, and soon becomes itself a tributary of the Rhine, which it even surpasses in volume when the two rivers unite downstream from Koblenz (Switzerland), opposite Waldshut in Germany. The Rhine, in turn, empties into the North Sea after crossing into the Netherlands.
