The district of Imst in the Tiroler Oberland is sub-divided into four main valleys: the Oberinntal including Imst and Haiming as the settlement centres, the Ötztal valley with its main settlements of Längenfeld and Sölden and the Pitztal and the Gurgltal. An important north-south transit route has led through the district since the Romans built a road through the Gurgltal and over the Fernpass and the geographical importance of this route has remained unbroken to the present day. From an economic point of view, above all the building trade and wood industry play an important role, while tourism dominates in the Pitztal and the Ötztal valleys and Sölden could be called a tourist hub. Put in a nutshell, the district of Imst can be described in superlatives: Sölden is the biggest community area-wise in Tyrol, the Rofenhöfe farms are the highest permanent settlement in Austria, the Ötztaler Alps are the most glaciated mountains in the Eastern Alps and Hermann Gmeiner founded the first SOS-Children's Village in Imst. Numerous landslides like, for example, on the Tschirgant and in Köfels are distinguishing features of the scenery. From the Ötztal an old mountain pass, the Timmelsjoch, leads to South Tyrol. Otzi, the approx. 6000 year-old glacier mummy was found on the Tisenjoch.
