CosmoCaixa

This is a kids science museum. You can sign up for activities a few days in advance by buying the tickets. They have an astronaut workshop and clik playroom which I highly recommend. The flooded rain forest is cool and so are all the exhibits which are designed beautifully and have wonderful interactive features. The cafeteria has kid friendly food and drinks.

Magnificent and Beautiful and Educational!

My husband & I took our 3.5 year old son there August 2015. We LOVED it!

A marvel! - It was a science museum, touch museum, architectural wonder, art museum, and even a mini aquarium/zoo combined into one.

Magnificent views of the coast. The architecture and set up of the entire museum simply relaxing, elegant, well thought out and beautiful. We spent about 3 hours which was enough time to enjoy most of it, but we and our son could have spent the entire day there! Definitely one of the highlights of our Barcelona trip.

Pros:
Architecturally and artistically beautiful
The rain forest was breathtaking
We tried the
Cost - so reasonable Admission only 4 euros pp and our son was free :)
The touch touch (toca toca) show was perfect for my 3 year old (cost 5 euros/adult). He touched creatures he normally wouldn't have! Chevy our instructor/guide was a gifted teacher and facilitator...thanks Chevy!

Cons:
None!

Highly highly recommended!!

Amazing museum! Great experience for adults and kids. We took our 1 year old daughter and even she enjoyed it. They have fascinating exhibits with countless hands-on, interactive activities. The amazon rainforest is like a mini-zoo. I highly recommend a stop at CosmoCaixa. Prices are very reasonable too.

This museum is an interesting mix between a science museum, a natural history or geology museum and even a zoo. The tropical rainforrest with living animals within the museum is fun for kids and adults. The arrangement of numerous scientific experiments seems to be orderless, but in this way there is a lot to explore and to discover. You can easily spend several hours in this museum without getting bored.

Great Museum, especially with kids, but interesting for the adults as well. The building is great after it's renovation with a large spiral ramp down the center of the 5 stories. Starting at the bottom, there is an enormous 2/3 story open area with exhibits, many of them taking advantage of the tall ceilings (like the pendulum slowly shifting and knocking down bars showing time).
Interestingly, they also have an exhibition called toca toca, where children (and adults) can see and touch animals. It was not expected in a science museum, but well done and fit with the living tropical forrest on display.
Our half day was not enough so we will be back as soon as possible.

One of the BEST science museums I've ever been to for hands on learning. Honestly, we wouldn't have thought to go if it wasn't for the fact that we were with kids in Barcelona. There are just so many things to see and do in Barcelona, but I am SO glad that we did. The location is a bit out of the way. But it's well worth it. Here are some highlights---
The architecture was beautiful!
Needed to escape from the heat with children.
The buffet lunch was just fabulous!
All the exhibits have great English translation.
Small, but very cool rainforest section with animals.

Near Tibidabao is the Cosmocaixa, which is well worth a visit. It has a rainforest within it showing its animals and its habitat. Excellent science displays - a mixture between the natural history museum and the science museum in London

A real gem of a eco/science museum. This was a nice surprise after spending a week visiting sites on the usual tourist itinerary in Barcelona. Both of my kids loved the hands-on exhibits in the expansive space and peaceful setting (it was relatively quiet, perhaps due to the holiday season). The rainforest and aquatic exhibits were impressive. To top it off, admission was free for kids up to 16 and so it was the least expensive visit of the week for our family of 4.
