The Loser Plateau (also referred-to as the Loser-AugstEck plateau) is part of the Totes Gebirge mountain range in the Salzkammergut of Austria.
The town, located 585 m (1033 ft) above sea level, is part of the Salzkammergut resort area in Austria.
In the west, the Upper Austrian part bordered on the Duchy of Bavaria, whereby the historic Innviertel belonged to the Bavarian dukes until the 1779 Treaty of Teschen, as well as on the Archbishopric of Salzburg in the Salzkammergut region.
Offensee is a lake located at the western end of the Totes Gebirge mountain range in Upper Austria's part of the Salzkammergut.
To the south the border runs from Lake Hallstatt up the Gosau Valley to Gschütt Pass, and from there downhill along the Rußbach Valley, separating the Salzkammergut Mountains from the Tennengebirge in the southwest, and the Lammer creek to its confluence with the Salzach near Golling.
