Our annual Family day 2018 will take place on Saturday 7th of July in the Efteling!
The welcome reception will take place from 9 am to 10 am in the Efteling Theater (at the right after the entrance). The park opens at 10 am and since you've already had the access control you can directly go into the park!

From 13 hours to 14 hours a comprehensive lunch will be served at the restaurant ' the courteous Herald ' in the Efteling hotel. After that you can visit the park up to 23 hours that night! In short this family day takes 14 hours and everyone will have fun!

We will set up a WhatsApp group for that day so that we can share information easily and quickly, we can help people if necessary. Participants will be able to find each other.

We have noticed that sometimes unknown persons register for our Family Day. This day is also intended to promote mutual contact and is therefore only accessible to members who have paid their dues.
Our volunteers also have access to this day.
