Pillersee Valley

In the south, the entire east–west running valley of the Rothache and Fieberbrunner Ache (Pillersee Ache) rivers, from the Grießen Pass in the east to the parish boundary between Fieberbrunn and St. Johann in Tirol in the west, also counts as part of the Pillersee Valley.

St. Johann, where the Fieberbrunner Ache empties into the Großache (Kitzbühler-/Kössenerache, eventually becoming the Tiroler Ache tributary of the Inn), is the junction with the Leukental valley of the River Großache.

In the south the edge of valley is delineated by the Kitzbühel Alps.

As a result, the Pillersee Valley lies on the geological boundary between the Northern Limestone Alps and the Slate Alps (Tyrolean "grass mountains"), made of grauwacke, in the south.

To the north the Pillerseestraße is the link to the Loferer Straße (B 178, Little German Corner–Wörgl).
