No one knows the fixed-roped route better than he does:
Günther Ausserdorfer is his name, a state-certified mountain guide and the wrench behind the Hans Kammerlander fixed-roped route!

The fixed-roped route is accessible from the beginning of May - end of October, you can find a super description of it
here.
