Jurapark Aargau -

The Jurasaurus Perimuk is looking for his lost lucky charm in the community of Biberstein. His friends help him in his search - and you?

Perimuk, the Jurasaurus has a task to solve: He has lost his lucky charm in the community of Biberstein. During his search, he meets his animal friends. Can they help him? You too can help Perimuk in his search. To do so, listen to the first part of the radio play at the starting board near Biberstein Castle and then follow the directions. If you follow the right path, a surprise awaits you at the end.

Here's how it works: The start of the Perimuk path is at the castle shop in Biberstein Castle. Buy a wooden ball from the vending machine (two-franc piece required), this will later show you the way. With a smartphone or tablet, you can scan the QR codes on the way and listen to the story. Together we will experience adventures and hopefully find my lost lucky charm.

The destination of the hike is the Juraweid inn. The route is suitable for all-terrain prams.
