The Areuse is the principal river of the canton of Neuchâtel, flowing through the districts of Val-de-Travers and Boudry. It is attested as Orose in 1107, Arosa in 1280, and La Reuse in 1595.
The river rises as a vauclusian spring at La Doux, near Saint-Sulpice (NE), fed by resurgence from the La Brévine valley (Lac des Taillères) and the eastern part of the Verrières syncline, at an elevation of 799 m. It flows 31 km before emptying into Lake Neuchâtel at the boundary of the municipalities of Boudry and Cortaillod, at 431 m.
