"The Winterstein, also known as the Hinteres Raubschloss or Raubstein, is a single, elongated rock massif in the Upper Saxon Switzerland. The medieval rock castle Winterstein was once located on the 389 meter high summit, of which there are still remains such as beam folds, carved steps and the cistern can be seen. [...] The Winterstein rock massif is a popular destination for hikes; the summit plateau can be reached via stairs and ladders." - de.wikipedia.org/wiki/Winterstein_(S%C3%A4chsische_Schweiz) The stolen castle is very clearly visible from the path. To get there, you should leave the bike behind. The way to the summit is via a ladder, not suitable for cycling shoes.
