The entrance is very cheap and there are a lot of things to do. Free entrance on the first Sunday of each month

At 4 EURO ticket (+30% discount if bought online) this is the best value for money / time spent in Barcelona (not including the free ones :D). You can easily spend 1/2 day here (or more if you go to the Planetarium shows or temporal exhibitions). Some great "games". The tropical habitat is awesome.

This is an awesome way to spend a rainy day in Barcelona. The exhibits are outstanding, and almost all of them are currently working. Plenty to do, and not just for young kids.

I specially recommend it to families with small children, although it's not addressed only to them. The entrance fee is very low.

Its cheap and it worth it...its good for children but not only. There are a lot of phisics and scientific experiment to understand the most important phisics phenomens. You can also buy some extra events such as a Planetarium experience, TocaToca (kids have the possibility to touch animals like mice and snakes; my little bro liked it). In the end... More
