Dollerup Bakker is a natural resort near Dollerup just south of Viborg. One of Denmark’s deepest lakes, Hald Sø, is beautifully embedded in the hilly landscape, which is right on the edge of the ice front separating the flat Western Jutland from the rather hilly Eastern Jutland. This is the reason for the quite big differences in height across the area.
The focal point of the area is Hald Lake, which is also one of Denmark's cleanest lakes and surrounded by Dollerup Bakker, which has been protected since 1947. Hald Lake is 342 ha and in some places up to 31 meters deep. Meet south and east, the lake is surrounded by steep slopes, where the terrain in some places reaches heights of over 80 meters.
