It is 695.4 m above sea level (NHN)[1] and lies within the Schwarzwälder Hochwald on the boundary between the counties of Trier-Saarburg (Rhineland-Palatinate) and St. Wendel (Saarland).

In the 20th century the Dollberg and the Schimmelkopf (Weiskircher Höhe) were seen as the highest points in the Saarland, both being measured at 695 m. According to more precise surveys by the State Office for Land Registration, Survey and Mapping ( Landesamt für Kataster-, Vermessungs- und Kartenwesen) in 2005, the Dollberg at 695.4 m is around 0.6 m higher than the Schimmelkopf.

[1] The summit of the Dollberg is covered by mixed woodland that blocks all views of the surrounding area.

Only a sign that describes it as the "highest point of the Saarland" marks the top.

[2] However, official maps neither record the name of the Dollberg nor its surveyed height of 695.4 m. In the area of the southwestern spur of the Dollberg, between the mountain and Nonnweiler, is the roughly 2.5 km long circular rampart of the hillfort of Otzenhausen, which was a Celtic refuge castle (oppidum).
