The Aare is the longest wholly Swiss river. It originates from the Oberaar glacier in the eastern Bernese Alps, flows through lakes Brienz and Thun, passes by the federal capital of Bern, is channelled into Lake Biel, follows the southern foot of the Jura range and finally flows into the Rhine at Koblenz, in north-western Switzerland. Passenger boats operate on the lakes as well as the river section from Biel to Solothurn.
Wherever the waters of the Jura tried to carve their way through the pleats of the Jura, gorges were created. And so it is with the Gorges de l'Areuse. Loudly splashing, the mountain stream Areuse is channeled through its gorge. A daring hiking path has been pinned to the cliffside to give hikers a good view of this natural wonder.
