It first opened in 2001 as an indoor family entertainment centre,[1] operated by the Gelissen Group.

Wunder Wald is an indoor area located in the same building as the Land van Toos with a ski theme.

The area contains playgrounds, a beer garden, and two attractions - a powered toboggan named "Maximus' Blitz Bahn" and Expedition Zork, a log flume.

The area features brightly coloured buildings containing shops, drink and food stores, a game gallery and an interactive show.

Based on Celtic mythology, the area includes the Bolliger & Mabillard-built wing coaster Fēnix.
