Unfortunately, you can not approach it directly. He is blocked by a fence, because the houses are collapsing next to it. But you can still look at it very well.
The Beuthenfall car park is located in the middle of the Kirnischtal. If you want to walk or climb the Häntzschelstiege, this is the shortest way there. You can also park mobile. But with my D1 network I have no reception there and you should take this into account. Only coins are accepted. With the E Plus network, someone parked their mobile there (mobile phone parking)
