The starting point of the long and challenging mountain tour on the Zitterklapfen is in Au-Argenau. From here, follow the path over the Vorsäß Boden and the Bergkristall hut to the Annalperaualpe. At the Annalperaualpe, a mountain hiking trail leads uphill to the sources of the Dürrenbach. After some time you pass the Steinkare, which is covered with snow until the summer and shortly after you have reached the rock entrance. Via the east nick, you climb the partly rope-secured rock up to the 2-kilometre long summit ridge. At the rugged and exposed ridge, vertigo and surefootedness is an absolute must, while you walk with careful steps to the summit cross. The view at the summit is unique and let you feel the vastness and a feeling of lightheartedness. Descent on the same route.
