Donderstenen is a family coaster built by Zierer in 2005. It replaces the former zierer coaster ''Avonturenslang'' Donderstenen is silencer and faster. It is better themed and also more popular. The rocks have faces and will turn around trees and a small pond. (photo) Donderstenen is the newest rollercoaster of the park. It is absolutely a must do when you are in this park.

 Did you know:
Avonturenslang, the former's ride was the children coaster of the park. Since it was an old ride and not good enough to be safe it has been sold to an other park in The Netherlands which made that coaster safe again. Donderstenen replaces the old Avonturenslang to give the children a new rollercoaster. With more speed indeed.
