Kalkalpen National Park

Wild and rich in species - on an area of 209 km2, the Kalkalpen National Park protects the largest contiguous forest area in Austria. 75% of the area is wilderness - that is unique in Austria.

Reichraminger Hintergebirge

The Reichraminger Hintergebirge is one of the largest closed forest areas in Austria - a sea of forest that has not yet been cut by public transport routes and settlements. Here we also find one of the longest intact stream systems in the Eastern Alps. Old Klausen and dilapidated Triftsteige still remind us of the use of wood in earlier times.


The Sengsengebirge is a northern outpost of the Alpine Limestone Alps. The approximately 20 km long main ridge reaches its highest point with the Hohen Nock (1,963m). The name Sengsengebirge is derived from the use of the forests as an energy source for the scythe smiths that used to be very numerous here.
