Our 2025 holiday: Anglesey Sea Zoo

After Beaumaris Castle and Plas Newydd, our third stop on our Anglesey day out was at Anglesey Sea Zoo. This is towards the southern tip of the island.

Anglesey Sea Zoo is an aquarium, with a focus on the sea creatures that you would encounter in the seas around Wales and the rest of Britain. As such, you won’t see many tropical fish, or massive sharks, but you will get to see the Lobster Hatchery of Wales – a conservation project to boost the numbers of wild European lobsters. Anglesey Sea Zoo was also the few aquariums in the world to successfully breed the native British species of seahorse, and you can see some of the seahorses on show there. There are also plenty of anemones, starfish, crabs, prawns, and various different species of fish.

Anglesey Sea Zoo is quite small, especially compared to Sea Life Centres or The Deep in Hull, and we got around it in about an hour. But it was interesting, and is certainly something to bear in mind for a wet day as it’s almost all indoors.

Accessibility

Anglesey Sea Zoo is mostly on one level and so those who struggle with steps should be able to see almost everything. There’s a modest car park, and (at time of writing) there were two free of charge medium-speed 7 kW electric car chargers available for visitors to use. The same bus that serves Plas Newydd gets within about a mile of the aquarium.

Nearby attractions

Next door to Anglesey Sea Zoo is the Halen Mon Sea Salt Factory – there’s a shop, and you can book on factory tours which run twice a day.

There’s also Foel Farm Park nearby, which is an open farm with play areas. We didn’t have the time to visit either of these when we went.
