This year (2025), the Pfalzel Scouts once again cleaned up this area, including removing the wooden structures. 80 kg of trash was disposed of at our expense. We don't know who's acting like this at this place. *Shakes head*

It's a shame that so much rubbish and leftovers from a "camp site" were simply left lying around here. There are other ways to be close to nature. Otherwise it would be a really great place.
