A really ancient tree. Many branches are overgrown with moss, the trunk has an unusually thick bark. The huge roots are not entirely harmless. Unfortunately, I could not sense any of the strong power of this oak tree, apart from a mystical flair, although I am usually very receptive to such things.

An impressive place of power, an incredibly special tree! There is a car park down by the road, then it is about a 1km walk uphill, you can also drive up and have the opportunity to park there again. The tree is on private property, that should be respected.

Nice mountain that is easy to walk in winter. For the last piece you may need Grödel with ice cream. Great views in several directions. At the top the paths are a bit confusing, with barriers - but you can find your way around.

When climbing up, the last third part of the route is quite steep, at the top of the circular route the route is fenced off, so we missed the given direction of the Way of the Cross a bit and had to go over a Climb over with barbed wire and locked gate. The descent afterwards over a very beautiful piece of mixed forest to walk on. Be sure to stop at the Gasthaus Windhaber (very good food and friendly) about 4 hours. hiked. In my opinion, the hike is wonderful.
