The ridge of Vorberge is located in the eastern edge of the Leine Uplands in the Lower Saxon Hills. It lies between the town of Alfeld on the River Leine to the southwest and Sibbesse on the Alme to the north.
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.
The unsettled hills of the Vorberge are crossed by several forest tracks and hiking trails which enable visitors to explored the wooded landscape. It is easily reached on the winding Landesstraße L 485 country road that branches off the B 3 in Alfeld, which runs northeast linking Alfeld with Sibbesse and with Hildesheim further to the north.
