Climbing, clambering and sliding underwater

In Atlantis you dive into an imaginative underwater world, made especially for adventurers young and a little older. Kids can climb along winding routes, crawl through tunnels, whizz down slides and conquer the highest spots. There’s always something new to discover, so there’s no time to get bored.

While you catch your breath, your kids move from one adventure to the next. There’s something for everyone: little ones find a safe spot to play, and the daring climbers can really let loose.

A complete holiday day out for the whole family

Atlantis completes your day at the Dolfinarium. Start with the impressive shows, meet our dolphins, walruses and sea lions up close, cool off at Waterpret and get to know the wondrous underwater world of the sea along the way. And when little feet are ready for something new, dive into the play paradise of Atlantis.

That way you experience animals, watery fun, play and discovery all in one day. A real holiday day out, rain or shine.

When can you come and play?

We’re working hard to open the doors of Atlantis this summer; the opening is expected at the end of July. We’ll share the exact date as soon as we know it, so keep an eye on our website and social media. See you soon!

Frequently asked questions about Atlantis

When exactly does Atlantis open?

We expect Atlantis to open this summer, most likely at the end of July. As soon as the exact opening date is known, you’ll find it here and on our social media.

What age is Atlantis suitable for?

Atlantis is a play hall for the whole family. There are challenging climbing and slide routes for older children and quieter spots for the little ones.

Is Atlantis indoors?

Yes, Atlantis is fully covered. A great option on warm summer days and on days with less sunny weather.

Is Atlantis included in the entrance fee?

Atlantis is simply part of your visit to the Dolfinarium; you only need a valid entrance ticket.

Do you need a separate ticket for Atlantis?

When the Dolfinarium is open, Atlantis is free to enter for visitors to the park. So you do need a valid Dolfinarium entrance ticket.

Outside the regular season, Atlantis may also open. If the Dolfinarium park itself is closed at that time, a separate rate applies for Atlantis. We’ll announce these prices later.

Do you have free access to Atlantis with your annual pass?

Atlantis isn’t automatically included in annual pass access. To let pass holders experience Atlantis too, you can go in and out for free until 25 October 2026, once Atlantis is open – and as often as you like, not just once.

After 25 October 2026, a separate arrangement will apply for pass holders. As soon as Atlantis’ prices are announced, we’ll let you know.

Is Atlantis wheelchair accessible?

Atlantis is a challenging play hall full of climbing, scrambling and sliding elements, with a lot of movement and changes in height. Because of this, Atlantis is unfortunately not, or only very limitedly, accessible for wheelchair users.

We think it’s important that you know this in advance, so you can take it into account when planning your visit.
