An interesting aquarium with lots of sea creatures to look at. Penguins and seals were a delight. I kind of feel that the dolphins' pool was too small for these magnificent mammals. Like whales, sharks and sea turtles, they belong in the ocean. There's a good restaurant, but it was loud and crowded. I think it was a holiday or there were simply too many tourists about.

the exhibition is not very big but educational with a good collection of rare species. The shows are entertaining especially the penguins going to picnic.

Although it was a little crowded, it was still such a fun experience! You even get to buy fish to feed the sea lion – definitely a highlight. Not to forget the penguin walk, which was super cute to watch! Just a heads-up: people start gathering really early, so it’s hard to get a good spot unless you’re there ahead of time haha. Overall, a fun and memorable visit – great for families and animal ...
