The Vorberge is surrounded by other uplands: the Hildesheim Forest to the north, the Sauberge to the east-northeast, Harplage to the east-southeast, the Heber to the southeast, the Sackwald to the south and the Sieben Berge to the west. Topographically, it transitions seamlessly to the last named range. Several streams rise within and on the edge of the Vorberge whose waters sooner or later find their way into the westward-flowing Leine or the northeastwards- running Innerste; it thus forms a watershed between the two rivers.
