The region around Frauenwald and Neustadt forms the most south-eastern part of the Thuringian forest proper. It is limited by state road B 4 in the northwest, and by a line along the rivers Talwasser (with Ilmsenbach), Neubrunn, and Schleuse. The adjacent Thuringian Slate Mountains form a geographically and geologically separate natural region, although they are often popularly referred to as a continuation of the former range. Populated places wholly within the region are Frauenwald, Allzunah, Neustadt am Rennsteig, and Oehrenstock. Parts of Stützerbach also reach into this area. Roads follow the Rennsteig, the mountain crests, or the valleys of the rivers.
