La ruée vers l'Or

The waltz is still danced here, but you don't have to shake the dance floor yourself, you just sit on one of the tree-trunk gondolas.
As soon as the journey starts, the gondola rotates freely around its own axis. Sometimes left and then right again or you won't stop turning wildly in one direction.

Hints:
Size restriction: from 1.40m (from 1.20m accompanied by an adult)
Age restriction: -no restriction-
