The new forest is growing back very well, and it's not the first time the Harz Mountains have been cleared. Look at it positively: you can see hiking trails, mountain bike paths, and cross-country ski tracks again, and you can see the mountains.

Anyone who wants to go up or down here needs to be well powdered, it is really steep, and not just for 20m

Old bridge "renovated" with new boards. A path leads here to the Schluchter Wiesenhütte and further up to the plateau of one of the two Schlufterköpfe, which leads to the Hanskühnenburg, among other places.
