Arnsberg Forest Nature Park

Nearly 350 km2 of the protection is forested and the park's wooded hills rise up to 581.5 m above sea level (NN).

The two forests form a densely wooded part of the Süder Uplands within the Rhine Massif.

Between these two valleys the park is situated between Möhnesee in the northwest, Rüthen in the northeast, Brilon in the east, Olsberg in the southeast, Meschede in the south and Arnsberg in the southwest; Warstein lies within the nature reserve.

To the north is the heavily forested region of the Haarstrang, to the east are the Brilon Heights, to the south is the Rothaargebirge, to the southwest is the Lennegebirge and to the west the terrain gradually descends towards Dortmund into the Ruhr.

These are the best known hills in the nature park because, unlike the other local heights they are shown on most of the maps and the specialised reference books.
