Cool down on hot days. Don’t forget to bring your swim wear!

After seeing those splashing dolphins, sea lions and walruses, you naturally want only one thing: to splash into the water yourself. Well, that’s great, because our Water Fun attraction is open in warm and nice weather! Children from three years of age can play, splash and slide down the slides here. And did you know that the Dolfinarium also has its own beach? You can have a great time at the Veluwemeer with fun playgrounds on the sandy beach and a terrace for the parents!

With eight wonderful, educational shows, including the impressive dolphin show Oceanica and four cool playgrounds, you will learn more about nature and experience an unforgettable day together with your family and friends.
