The Plackwald is a ridge of hills, up to 581.5 m above sea level (NHN),[1] and part of the Rhenish Massif in the counties of Soest and Hochsauerlandkreis, North Rhine-Westphalia, Germany.

[2][3] The Plackwald is a high, flat-topped ridge, roughly 500 to 550 m, that runs eastwards from the Großer Berg near the Arnsberg village of Oeventrop over the Warsteiner Kopf and Nuttlarhöhe to the Brilon Plateau.

In the Nuttlar Bowl, quartzitic argillaceous and greywacke slates of the Arnsberg Beds of the Namurian stage form the subsoil.

As a result the climate in the Plackwald is harsher and, with around 1,000 mm of precipitation annually, wetter that in other areas of the North Sauerland Uplands.
