The Untersberg rises at the rim of the Northern Limestone Alps, immediately at the Salzburg Basin and the broad Salzach Valley. Neighbouring peaks are the Hoher Göll in the southeast and Mt. Watzmann in the south, beyond the Berchtesgaden Basin. In the northwest, the Saalach Valley with Bad Reichenhall separates it from the Hochstaufen massif of the Chiemgau Alps. About two-thirds of the area, including the Berchtesgaden Hochthron peak, is located in Germany, while the northernmost steep edge above Salzburg belongs to Austria.
