The Hexenkopf lies on the northern chain of the Samnaun Group between the valleys of Paznauntal in the north and Oberinntal in the south.

To the north another ridge to the Plattkopf (2,893 m) separates the alpine meadows of Hinterflathalpe in the west from Berglialpe in the east.

The Hexenkopf is largely composed of mica-rich slate gneiss, which is interspersed with veins of pegmatite and other granitic rocks.

From the Masnerjoch col there is a waymarked route running initially westwards, and then along the northern arête of the Hexenkopf to the top.

The Masnerjoch may be reached from the Hexensee Hut, from the Kölner Haus (1,965 m) near Serfaus or from the north, from See in the Paznauntal valley.
