The fortress island near Herwijnen (Gelderland) has been transformed into a new and challenging theme park for young and old! Aim: to put geology in front of a large audience. It is entirely devoted to navigation and cartography, phenomena that the museum wants to make understandable for children. The role of parents is limited: they may at most read the text on a sign.
For example, children can turn a four-dimensional globe to see how continents and oceans are formed. One of the outdoor activity’s is the ‘salmon maze’. Children do not come out because of their intuition, but by following a fragrance trail. Just like a salmon looking for the river, they have to smell the way out: navigating with your nose!
