Schruns is a municipality in the Montafon valley (altitude 690 meters), in the Bludenz district of the westernmost Austrian state of Vorarlberg.

To the west is the famous Zimba mountain, often called the "Vorarlberger Matterhorn," which is very popular among climbers and hikers.

The Litz river, a tributary of the Ill river flows through the town. A side valley, the Silbertal, stretches to the east of Schruns. The area has a high mountain massif accessible by train and ski-lifts.

To the north is the Bartholomäberg, to the south St. Gallenkirch, and to the west Tschagguns. The nearest larger municipality is Bludenz. About 45.2 percent of the area is forested, with 18.1 percent mountainous.

Since 2012/13, Schruns has been part of the FIS Snowboard World Cup, which takes place annually in December. During the daytime, visitors can watch snowboard cross races up on the Hochjoch of the Silvretta Montafon ski area. In the evening, concerts are held in Schruns.

Schruns is a hotspot for mountain biking and trail running. For more than 10 years Schruns has hosted the M3 Montafon Bike Marathon, with over 500 bikers.
