I'm looking for a play group or indoor playground for kids in the Eglisau, Bülach, Airport area, that is ideally also open on Sundays.
Any recommendation or a place to search is appreciated. Google is of not much help, as "Spielgruppe" and Kinderparasies can mean many things, apparently.
Spielgruppe is the wrong word to use. That is a set group they attend as a pre-kindergarten.
All the indoor playgrounds are open on Sunday and very busy.
But mostly you will have to stay there with your children.
Bouncelab is a hit with bigger children. They also have things for small ones but it will be busy on a Sunday https://www.bouncelab.ch/trampolinhalle-rueti
