The Zwieselbacher Rosskogel is situated in the area of three high valleys: north of the summit is the Kraspes valley (Kraspestal) and, to the east, is the Gleirsch valley (Gleischtal), both side valleys of the Sellrain. To the west of the mountain lies the Zwiselbach valley (Zwiselbachtal), a side valley of the Horlach valley (Horlachtal), which, in turn, opens at Niederthai into the Ötztal valley. From the crest that runs from north to south separating the Zwieselbach and Gleirsch valleys, a side ridge branches off at the Zwieselbacher Rosskogel in a northeasterly direction on which another three-thousander rises just under one kilometre away, the Rotgrubenspitze (3,040 m). On the ridge north of the summit are the peaks of the Weitkarspitzen (up to 2,947 m) and the Kraspesspitze (2,954 m). On the prominent arête to the south at a distance of about 750 metres is another striking peak, the Gleirscher Rosskogel (2,994 m).
