The Gleirscher Rosskogel is situated on the crest between the Zwieselbach valley (Zwieselbachtal) to the west as the Gleirsch valley (Gleirschtal) to the east. The former is a side valley of the Horlach valley (Horlachtal) which opens into the Ötztal below Niederthai. The Gleirsch is a side valley of the Sellrain. The lowest point of the north-south ridge between the Zwieselbacher and Gleirscher Rosskogel is at a height of 2,946 m. Southeast of the summit is the col of Gleischrjöchl (2,750 m), which separates the Gleirscher Rosskogel from the Schartkopf (2,831 m), also called the Samerschlag, and the Zwieselbacher Grießkogel (3,066 m).
