Interesting mixture of aquarium and maritime museum. History of fishing and whaling is important to show the impact these have had. Spread across 5 levels. Good for families with kids. A few documentaries where screened during our visit. Amazing views from the rooftop and upper levels. Restaurant and cafe were closed when we visited though. Museum shop on site with branded products for kids and gifts for adults.

Got to see sea lions and many other fish and mammals. They do feed the sea lions at certain times per schedule. There is a giant tank with sharks, sea turtles and so so much more. Tons to see, very similar to Shedd Aquarium in Chicago but smaller. Place to eat and drink also. Highly recommended!

Very friendly staff at reception - the woman who served us was very gentil and kind, by far the kindest person I have met in the Basque Country so far. The aquarium was clean - they had a good display of the sea life and local history within their museum. I would say, that it is very similar to the Atlantis in Dubai. Although you can’t touch any of the sea life and the animation wasn’t great… Though I do recommend it.
