The Lauteraarhorn is a peak (4,042 m) of the Bernese Alps , located in the Canton of Bern . Together with the higher Schreckhorn , to which it is connected by a high ridge, it lies between the valleys of the Lower Grindelwald Glacier and the Unteraar Glacier, about 10 kilometres southeast of Grindelwald, the closest locality. The Lauteraarhorn belongs to the Aaremassif and is surrounded by large glaciers: the Lauteraargletscher and the Strahlegg-Gletscher (both feeders of the Unteraar Glacier) and the Obers Ischmeer (tributary of the Grindelwald Glacier). Being off the main ridge of the Bernese Alps, all the glaciers surrounding the Lauteraarhorn and the Schreckhorn are part of the Aare basin. The Lauteraarhorn is the second highest summit (after the Schreckhorn) lying wholly within the canton of Bern. Administratively, it is split between the municipalities of Grindelwald and Guttannen .
