The Graz Highlands or Graz Mountains (German: Grazer Bergland) are a low mountain range north of the Styrian state capital of Graz in Austria. It is part of the Central Alps and forms the start of the Prealps East of the Mur. From a geological perspective, regions on the west bank of the Mur, which are clearly separate from the building of the Styrian Prealps, belong to the Graz Highlands.
Location
The Graz Highlands are a low mountain massif in the north of the Styrian Hills and lie mainly east of the River Mur.
The core area of settlement is the Passail Basin, the adjacent Semriach Basin to the southwest and the Teichalm region to the north.
in the west by the Mur valley from Mixnitz to the northern city limits of Graz. By geological definition certain parts west of the Mur are also counted as part of the Graz Highlands, especially those which belong to the Graz Palaezoic, such as the PlabutschBuchkogelzug
in the north by the Breitenauertal (valley containing Breitenau am Hochlantsch) and the valley of the Gasenbach. Other definitions view it as the line from Mixnitzbach via Teichalm to Gasen
