Nice, not too long hike with a wonderful view, which is also doable with children. The Burgstall Gorge is a special highlight for off-road children but also for adults. An approx. 20 m long rock crevice for slim people. But of course also the “summit victory” for young and old.

The cross is a little off the path, but you can't miss it on the ascent to the summit stone.
