The Neuburg Forest is actually a range of foothills of the Bavarian Forest on the far side of the Danube and thus forms a perimeter zone of the Bohemian Massif. It lies south of the Danube and extends for almost 30 kilometres from the lower Vils valley near Vilshofen to the lower Inn valley near Passau, and in the southeast to Neuburg am Inn. In the north lie the steep slopes of the Löwenwand near Seestetten (southern right bank of the Danube). The average width of the hill range is just under seven kilometres. The Neuburg Forest covers an area of 186 square kilometres. On Austrian territory east of the Inn, the [[Sauwald]] is its continuation. Taking that into account, the Danube has cut its way through the foothills of the Bavarian Forest for a total length of 70 km.
