The Mahlberg is a mountain in the northwest of the Northern Black Forest and, at 612.5 m above sea level (NHN),[1] is the highest point in the Baden-Württemberg county of Karlsruhe and the parish of Völkersbach.

It rises between the Gaggenau villages of Freiolsheim in the northwest, Moosbronn in the east and Michelbach in the southwest.

The Moosalb flows past the Mahlberg to the east and the Michelbach runs past it to the south, the little tributaries of which - Obersbach, Walkenbach, Litzelbach and Eckbach - rise south and southwest of the mountain.

Not far from the tower there is a memorial site with the grave of two Wehrmacht soldiers who died on 10 April 1945 when the radio station on the mountain was shelled during the Second World War.

In the area of its entrance there is a request for small donations to assist in preserving the tower.
