Great view from the upper platform of the Vogtland Arena over Klingenthal. Admission is 1 euro to visit from below, the trip to the top costs 7 euros (total). The trip to the upper platform of the ski jump is particularly recommended. There is an elevator at the lookout tower, but you can also use the stairs. We were lucky enough to watch the jumpers training and were amazed at how high the whole thing is.
I found the ride disappointing. Like a roller coaster, you rattle up bumpy, but it goes down just as slowly. I was expecting a little more action. The view from above is wonderful. If you use the stairs, you have new impressions on every floor.
