It’s been a while since I last visited Wasalandia. From what I understand this is a place for children under 14. Older than that and they will be bored to death. Small kids will have fun though. It’s quite expensive though as everybody pays for the entrance, after that (almost) everything is free.

prices (2006):
Adult or child taller than 120 cm: 17 €
Child, shorter than 120 cm: 12 €
Senior citizen: 6 €
Infant, younger than 24 months: Free
