To the north the Alpine Foreland forms the boundary from the river Lech to the river Loisach. The Lech forms the boundary in the west from its exit into the Alpine Foreland downstream as far as Reutte. The Loisach borders the Ammergau Alps in the east, southeast and south from its exit into the Alpine Foreland upstream as far as the Ehrwald Basin. To the southwest the valley of the Zwischentoren forms the link between the Ehrwald Basin and the Reutte Basin (Talkessel).
