Östlicher Sengsengebirgsgrat © Sieghartsleitner

The Sengsengebirge is a northern outpost of the Limestone Alps. The ca. 20 km long main ridge reaches its highest point at the Hoher Nock (1,963 m).
The name Sengsengebirge can be traced back to the use of the forests as a source of energy for the numerous scythe smithies once located here.


Hintergebirge © Mayrhofer The Reichraminger Hintergebirge is one of Austria's largest distinct forest areas - a sea of forest, which has not yet been dissected by public transportation routes and human habitation. Here, you will also find one of the longest intact stream systems of the Eastern Alps. Old shelters and overgrown trails remind us today of how wood was used and harvested in earlier times.
