The Sieben Berge are surrounded by the hills of the Hildesheim Forest to the northeast, the Sauberge to the east-northeast, the Vorberge to the east and the Sackwald to the southeast. To the west runs the valley of the Leine, behind which rises the Ith ridge. Topographically it transitions to the Vorberge almost seamlessly. Within and on the edge of the Sieben Berge rise several brooks whose waters flow, sooner or later, into the Leine.
