Hall of Nature

Entrance with centre ticket
Watch the everyday life of wood ants and chicken, check out the tropical fish, create fascinating patterns with the water printer and spin the fog swirls

AHHAA's Hall of Nature is the only indoors place in the world where you can watch 20 000 wood ants buzzing around (don't worry, they're safely in their ant hill!). It is also a home to tropical fish, corals and other sea animals from the Red Sea (who live in a whopping 6000-litre fish tank). And if you're lucky, another fluffy chicken might hatch from an egg just before your eyes!

Our water world is great fun for big and small visitors alike: create whirlpools, shoot from the water cannons and build a functioning water works system.

There is also a special building area with soft and colourful building blocks, for our youngest visitors. But all the other architecture enthusiasts are welcome as well!
