The Emmental Alps are a mountain range in the western part of the Alps, in Switzerland. They are located north-west of the Brünig Pass, mainly in the cantons of Lucerne, Bern, and Obwalden, with a small portion in the canton of Nidwalden. The highest summit of the range is the Brienzer Rothorn, which is also the highest point in the canton of Lucerne. The range is named after the Emme valley (German: Emmental). In the north-west corner one finds the relatively low, but widespread, and very furrowed  Napf.
