The Kollwesshöh is, at 181.4 m above sea level (NN),[1] the highest hill in the Stemweder Berg, the smallest and northernmost range of the Central Uplands in Germany, and also the highest point in the North German Plain north of the Bückeberge.

As a result of transcription errors between maps in the 19th century there were various versions of the name, but eventually the name Kollwesshöh was settled on.

The Kollwesshöh is part of the Stemweder Berg which in turn lies within the Dümmer Nature Park.

The Kollwesshöh may be accessed, for example, from Westrup by taking forest tracks heading northwest that link it with the Scharfer Berg.

Just under 1 kilometre north of the Kollwesshöh on the White Way (Weißer Weg) is a Bronze Age tumulus that is worth seeing.
