The climbing wall has routes for both children and adults. There are six routes which will be replaced about once a year.
The climbing wall is:
- A total of 144 sqm. on two sides
- 15.6 meters high
- 5 meters wide at the front and 3.75 meters wide on the side wall
- some 400 grabbed spread out on the climbing wall, as well as set up volumes, which operate like small hills.
