The hill ranges around the Reuberg are the Duinger Berg to the northwest, Külf to the north, the Sieben Berge to the east, the Steinberg to the southeast, the ridge of Hils to the southwest and further to the west the knife-edge of the Ith, part of which belongs to the Weser Uplands-Schaumburg-Hamelin Nature Park. The valley of the Glene, a southwestern tributary of the River Leine, runs over to the Duinger Berg.
