Giant marble run

Where baubles make children's hearts beat faster

What looks like pure fun is full of technology and attention to detail: the ball track by artist Stefan Grünenfelder, made possible by the Roger Federer Foundation, has 14 clever mechanisms that allow the balls to crank, pull, climb and dance even in winter. They roll 145 meters through the adventure, without beginning and without end. And best of all: admission is free.

And who says that only balls get rolling? At the Pradaschier adventure mountain, children's hearts are often full of joy, curiosity and play. Just come along, try it out and roll home with a smile on your face.
