The valley opens to the east of the district capital Bludenz and is characterized by the south and north steeply towering mountain ranges of the Lechquellen Mountains and the Verwalls mountain range. The Alfenz flows through the Klostertal from Stuben am Arlberg (district of Klösterle/ Arlberg) to the Ill at Bludenz. The bottom of the valley is rising steadily, which is reflected by the fact that the sea level of the settlement areas ranges between 600 m in the west and 1,400 m in the east.
