The Oberbergtal joins the main valley from the left at Milders (1,026 m, Neustift im Stubaital). The head of the valley is formed by the glaciated Alpeiner Berge (Schrankogel 3,497 m, Ruderhofspitze 3,474 m, Östliche 3,416 m and Westliche Seespitze 3,355 m), which surround the Alpeiner Ferner and several side glaciers. Heading down he valley the line of mountains on the right descends gradually to the Brennerspitze (2,877 m) and on the left runs over the Hohe Villerspitze (3,087 m) to the Hoher Burgstall (2,611 m).
