Experience shows that children between the ages of 4-12 years have the most fun at SEA LIFE. 

But of course this also depends on the children's interests and other factors and can also be very exciting for some older children.

Our exhibition is located inside the building.

At the booked time and day you go to the group entrance with your child birthday group. There you will pay for the children's birthday party and receive a welcome message for the birthday group. Here you will also hand over the treasure you want to have hidden in the chest if you haven't booked an extra one.

For hygienic reasons, you are not allowed to bring your own food to the restaurant (except baby food). 


Yes, you are allowed to take pictures in our aquarium. However, please make sure to turn off the flash beforehand, as marine life is very sensitive to bright light.
