We were in the Algarve for a week in October. The weather was still hot (well... Hotter than the average summer in Glasgow!)
We had exhausted the beach, pool etc and were looking for somewhere a bit different to spend some time (and maybe even tire out a 2yo and 4yo?)

In terms of pricing, it was really cheap, €7 for all four of us. Good start!
The staff on reception were very friendly.

The exhibits were interactive and all the instructions were in Portuguese and English; they were probably a bit too advanced for our kids but were interesting enough.
The outside area was really nice - beautiful view over the water and a pirate ship/water exhibits and a lighthouse - all providing a great area for kids to run around and play whilst getting a wee bit of science into them too.
I would go back. We ended up being there for about 2 hours - and we could have probably stayed longer had we not needed to head for cold drinks.

Brill my 4 year old grandson really enjoyed children's area lots of experiments especially in outdoor play area.

Fabulous hands on science museum for the kids. Water features, a yellow submarine, a lighthouse and loads of other geographical and science hands on exhibits. My 3 year old spent 3 hours on the go here with barely a stop. Can't praise this place enough and it was 7 euro for a family.
