The Dörenberg, the highest elevation in the centre section of the Teutoburg Forest, lies between Bad Iburg and the Georgsmarienhütte village of Oesede, whereby the boundary of both parishes runs over its southern flank, close to the summit. East of the hill, the B 51 runs between both settlements in roughly a north-northeast to south-southwest direction. The summit can be reached on woodland tracks from this road.
