The Hafner massif rises between the Radstadt Tauern and the Mur valley of the Salzburg Lungau region in the north and the Carinthian Malta valley in the south. It comprises Kleiner Hafner () and Großer Sonnblick () subpeaks, lying just to the southeast. In the south, the Malta valley leads to the Reißeck Group, while in the east, Katschberg Pass separates it from the neighbouring Gurktal Alps.
