The Kahlersberg is a 2,350 metre high mountain in the Northern Limestone Alps (Hagen Mountains) in the Berchtesgaden Alps on the border between Germany (Bavaria) and Austria (Salzburg).
From the west a steep, marked climb (Route 496) runs through the so-called Mausloch ("Mousehole") to the summit. The summit can also be reached along the Eisenpfad ("Iron Path"), a path which approaches from the southwest, from the Landtal valley, is very steep in places and has old markings. A trackless descent variant runs from the Fensterl, a wind gap with a striking, small pit (in the right of the picture; the fourth wind gap left of the summit), northwards and down into the bowl between the Kahlersberg and the Hochseeleinkopf. This descent drops down mainly over steep scree.
