Unterperfuss is situated opposite of the market town of Zirl. Unterperfuss became an administrative independent village in 1832. With its 2,2 km² surface area and the scanty number of population, Unterperfuss belongs to the smallest villages in the Tyrol. The Melach River, which runs through the Sellraintal, forms the natural border to neighbouring Kematen. The strong impact of the agricultural sector is best reflected in the landscape with its fields and pasture lands. Due to the initiative of some progressive farmers Unterperfuss has become a centre for equestrian sports with excellent facilities.
