We were really looking forward to our trip to this aquarium as we had just spent two weeks driving around Europe, and our visit here was supposed to be a nice way to end our journey before getting the ferry home. Unfortunately, we were beyond disappointed. Firstly, it was busy, which we expected as it was a Saturday, but it was ridiculously crowded, and we couldn't get near enough to see anything at all. We were getting pushed and shoved everywhere, and having our daughter out of the pushchair to explore just wasn't an option. I would have thought that following COVID venues such as this would learn not to overcrowd but people forget quickly I guess. Secondly, and further to the first point, there are very few fish in this aquarium, which I think made the crowding worse because there were so many people gathered around so few exhibits. They have the big tank which is really where all the fish are. There are a few small tanks here and there with some fish in (I assume, I didn't get close enough to see any). While impressive, you'll see more in the way of people's silhouettes and phone camera flashes than you will fish. "It's such an enormous aquarium, how can there not be many fish?" you might ask. Well, the place is HIGHLY padded with video projectors playing loops of fish on the walls. I mean you could probably watch the same videos at home without getting knocked about every which way. As far as I could tell all the videos were CGI also so not even real sea creatures. As well as the videos most of the aquarium is just educational displays, which I have seen in much smaller aquariums that have 20x more tanks. Thirdly, the accessibility at this place is an absolute nightmare. I wouldn't recommend for wheelchair users. We struggled with a pushchair. It is very unclear which way you are meant to go most of the time. The lifts are archaically slow to the point I wondered if there was just a person pulling at ropes to power them. Most of them are only big enough for one family, other than a big one that is slowed down by a terrible CGI film they play - and I'm sure they wait until the video is over before they let you out of the lift. We saw people being reprimanded by the staff for taking pushchairs on the escalators, but there really was no other choice other than forming a looong queue outside the elevator. We carried our daughter's pushchair up the stairs because we gave up waiting on the lifts. There are next to no ramps, so even when there are a few a steps, someone in a wheelchair would have to wait to use the elevator. We did enjoy seeing the seals, however, the seal tunnel filled up very fast, and we thought there would be show, but it seems like it is just a stream that you watch on videos. Of the reptiles we saw the alligators but none of the others because there was really no way we were going to be able to get through the crowd to see anything. We walked past the penguins, but again there was no way we were getting through the swathes of people to see them. Overall, just a bad experience and it was such a shame for the finale of our trip to fall so flat. 30 Euros each is extortionate for what they actually have here. I think even if it hadn't have been so excessively busy we would have been disappointed at the lack of tanks and fish for 30 Euros. The shop has some nice stuff in it; unfortunately, we didn't really feel like giving any more of our money to this place.
