Frequently Asked Questions

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

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

For example, we also offer children's birthday variations for different age groups. Please be sure to let us know when booking if your wish differs from the normal treasure hunt.

We recommend our normal treasure hunt for children who can read (mostly 8-12 years).

Our location is housed indoors, a children's birthday party can be celebrated at SEA LIFE regardless of the weather.


At the reserved date and time, please go to the SEA LIFE Hannover entrance. There you register and we will have a welcoming for you and your birthday group (unfortunately, this can only be guaranteed for punctual groups).

Then off you go on your own exciting treasure hunt through SEA LIFE.

It's best to plan about one and a half to two hours for your stay.

On the way out of SEA LIFE to the Bistro, you will pass through our souvenir shop. As this is always on the way, it's best to plan some time for the children to look around.

In the case of a booked treasure hunt, each birthday group receives a welcome from us and then starts the treasure hunt on their own - therefore at least one adult is necessary as an escort. But don't worry, the treasure hunt should keep your children well occupied.

We don't organise full themed birthday parties, but these can of course take place at our centre. For example, these invitations could include having all the children come dressed as jellyfish, starfish, clownfish, other sea creatures or even pirates!

Yes, we have a small café with a selection of drinks, coffee and cake. If the weather permits, there are also nice seats on the terrace in front of the cafe, with a view of the pond. Unfortunately, it is not possible to reserve a seat.

For hygiene reasons, food you bring with you may not be eaten on site (except baby food).

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

The treasure for the treasure chest is included in the basic package for each child.
The treasure contains at least three items per child from our souvenir shop.

The basic birthday package costs €95.
