At the foot of the Rösterkopfrises the River Ruwer, a right tributary of the Moselle.
The watershed between the Moselle (Feller Bach and Ruwer) and the Saar (Wadrill/Prims) runs through the Osburger Hochwald. The B 52 federal road and A 1 motorway, as well as several local, county and state roads, run through the forest. There are rescue points for the emergency services at various prominent places in the forest.
