phew .... not easy to find. And then again. The trick is to find the signs that actually point the way. A little patience and everything will be fine. Ultimately, clearly visible paths lead there. And when you stand in front of it, the signs show that you are right. A little further away and "around" the signs are sparser. And smaller than that in the photo.
The system itself is then hardly recognizable without the instructions. The ditch around the ski jump is max. 60cm deep - and thus a gentle wave in the forest floor.
Again, it is a beautiful forest and just very quiet. It's worth it anyway - somehow ;-)
CAUTION. The position on the map is not that precise. The ski jump is in the middle of the forest. Nevertheless, it can be reached via paths.
