Mallnitz high-altitude health spa and winter sports resort is located at an altitude of 1,200m, nestling amongst the wonderful mountains of the Hohe Tauern.

The Mallnitz and Tauern valleys carve through the Goldberg and Ankogel High-Alpine Groups. The municipality covers an area of around 110km2.

The constituent parts of the Municipality of Mallnitz are Mallnitz itself, Stappitz, Rabisch and Dösen.  Mallnitz is separated from Stappitz by the Mallnitz and Seebach streams.

Whereas Mallnitz is located on the right bank of both streams, Stappitz lies to the left.  Rabisch is located just where the Mallnitz valley slopes down into the Möll valley; and Dösen can be found on the broad slope of the Dösen valley.
