The Stubai Alps is a mountain range in the Central Eastern Alps of Europe. It is named after the Stubaital valley to its east. It is located southwest of Innsbruck, Austria, and several summits of the range form part of Austria's border with Italy. The range is bounded by the Inn River valley to the north; the Sill River valley and the Brenner Pass to the east ; the Ötztal and Timmelsjoch to the west, and to the south by tributaries of the Passer River and Eisack.GeographyThe Stubai Alps are named after the Stubai valley, which runs from south of Innsbruck in a southwesterly direction deep into the mountain range.Important parts of the Stubai Alps show signs of glaciation. The northern part around the Sellrain valley and the Kühtai is now only lightly glaciated and a popular ski touring destination (Zischgeles, Lampsenspitze, Pirchkogel, Sulzkogel). The High Stubai around the upper Stubai valley is still heavily glaciated and a classic high mountain touring region in the Eastern Alps. Here there is a glacier ski area on the Stubai Glacier.
