Zahn, Mountain summit in Oberammergau, Germany.

Zahn is a group of jagged rock peaks on the Brunnberg ridge in the Ammergauer Alps, on the territory of Unterammergau and Oberammergau. The highest point reaches 1,619 metres, rising about 136 metres above the surrounding terrain. The grey rock faces are steep and pointed, with green vegetation on the lower slopes.

The Zahn peaks belong to the Brunnberg ridge in the Ammergauer Alps, on the boundary between Unterammergau and Oberammergau. The sources record no dolomite here and give no geological dating; the summit stands at 1,619 m, about 136 m above the surrounding terrain, with a base roughly 2.8 km wide. The Zugspitze lies 18.3 km to the south-west, Garmisch-Partenkirchen 11.5 km away.

The name Am Zahn refers to a group of rock peaks on the Brunnberg ridge, not a single summit; the German word Zahn means tooth. The peaks lie on the boundary between Unterammergau and Oberammergau. Climbers know the area as the Zähne, where numerous climbing routes exist.

The trail starts from Pürschlingssparkplatz parking area at about 895 meters elevation with several marked paths to the summit. Good hiking boots and reasonable fitness are recommended, as the route becomes steeper higher up, particularly in the final sections.

The Zahn is not one peak but a group of rock spikes on the Brunnberg ridge, and numerous climbing routes exist on these teeth. Hikers can reach them fairly easily from the Kolbensattel; the traverse of the whole Brunnberg ridge is the harder option.
