If you want to escape from the bustle of the Dachstein, the western Tennengebirge is an option. This small area, which rises steeply from the valley leading to Salzburg, is part of the Northern Limestone Alps. The area is a clear example of a karst region: no water on its surface and has many caves, including the world's largest ice. The highest of its summits is the Raucheck, 2431 m. Thanks to some ten huts, the  Tennengebirge is easily accessible for the seasoned hiker.
