I have been to this amusement park several times when I was a child/teenager. I always thought it…read morewas great fun, especially the bob slide and the Marienkäferbahn, a very light version of a roller coaster. My favorite is still, undoubtedly, the Wildwasserbahn/wild water slide/log flume. But beware: You will get quite wet. When I went there as an adult, the general feeling was: Boring. It wasn't very crowded, as we went during the week, but most of the rides seem to be aimed more at children and families. The wild water slide was still fun and I also enjoyed the Devil's Mine quite a lot. Prices range from 19,90 Euros for kids (Under 3 year-old are free) to 23 Euros for adults (24 in July and August). There are special offers for groups and yearly tickets for those planning to visit more often!
