See the best of British marine wildlife at this native marine aquarium! A Splashing Day Out whatever the weather!

Native British marine aquarium, featuring the Best of British marine wildlife!

Ever wondered what lurks in the seas around the coast of Wales and Britain? Would you like to know all about British seas and the kind of creatures that live in them? Want to see catsharks, seahorses, octopus, lobsters and other exciting British marine animals up close and learn all about them? Then this is the place for you!

As well as seeing all our animals, you can learn all about British marine habitats and the research and conservation work which is helping to save them, both here and further afield, including our British seahorse breeding programme and the Lobster Hatchery of Wales. Explore British marine habitats including a colourful reef and incredible invertebrates in the No Bone Zone, the wolf fish lair, a real crashing wave, a creepy shipwreck and a kelp forest full of big huge fish.

Opening times

We're open every day during the season, including bank holidays!

The opening times are:

10am-4.45pm (last entry), hot food served in the cafe until 4pm.

We are open from February half term until early December. During quieter periods, such as between February half term and Easter, we may close earlier, so we recommend phoning in advance to check the opening times if you're visiting outside school holidays and planning to come late in the day.

Please telephone or check our website or Facebook for further details.
