Grandpa & Grandma day

On Saturday, May 2, 2026, Jan Klaassen wants to pamper all grandfathers and grandmothers: On this day they only pay half the price for admission! The perfect time to go out for a day with the grandchildren.

Pampering afternoon
Follow the route together on the treasure map and go on a journey full of fantasy. Travel back in time, for the digital age. Slide off the turbo slide together and then rest for a while at a fun puppet theater performance.

Opening hours
Jan Klaassen's Land is open on Grandpa & Grandma day from 10 a.m. to 5 p.m.
