Serfaus is a municipality in the district of Landeck in the Austrian state of Tyrol. It is well known as part of the ski-region "Serfaus-Fiss-Ladis", which was formed when Serfaus teamed up with the two nearby municipalities of Fiss and Ladis in 1999. Serfaus is also known for its small hovertrain subway system, the U-Bahn Serfaus. With four stations and a length of 1280 m (the second-shortest underground train line in the world) it allows for a complete ban of cars within the town, while at the same time maintaining the village's attractiveness to tourists, particularly skiers.

Serfaus is a small town located on a plateau 500m above the upper Inn valley in Tyrol, western Austria. Above the town a high ridge rises, linking Mount Furgler (3004 metres above sea level) with Mount Schönjoch (2491m).
