The Großer Kellenberg is the westernmost hill on the main chain of the Wiehen that attains a height of over 200 metres. It is thus also the highest hill in the Lower Saxon part of the main chain of the Wiehen Hills. That said, the hill is not the highest point in the borough of Melle - this is in the Melle Hills, that lie to the west but are just a secondary chain of the Wiehen.
