We worked out an attractive formula for our proud grandparents holders of a ZOO pass: the grandchildren's card. You only pay € 55 for a ten-entry card*. This allows you to come ten times with one grandchild, or once with ten grandchildren.
Actually, you should understand the word 'child' in the broad sense. The card is indeed valid for offsprings up to and including 17 year olds. Your little pride and joy under 3 years get in free.
Besides unlimited access to Antwerp ZOO and Planckendael, with your ZOO pass you will enjoy a cartload of great deals.
Passes can be purchased at the ticket windows or from the member service of Antwerp ZOO and Planckendael.
