To the southeast and adjacent to the Regen Depression and Anterior Bavarian Forest is the Passauer Vorwald and, beyond it, the Abteiland (Abbey Land), which on average is only a little hillier than the Regen valley. In the north of the region are the towns of Grafenau and Freyung, to the south is the Neuburg Forest, south of the Danube between Vilshofen and Passau. In the east, roughly from Waldkirchen, the Abbey Country transitions into the Wegscheid Plateau, which flows seamlessly into the Mühlviertel region of Lower Austria. This reaches a height of 948 m in the Frauenwald. To the west the Passauer Vorwald, south of the High Bavarian Forest and opposite its northern and northeastern perimeter mountains, descends into the Lallinger Winkel (Deggendorfer Vorwald) around 400 metres lower.
