Anglesey Sea Zoo is a unique aquarium with over 40 tanks displaying the best of British marine wildlife! Don’t expect to see large sharks, tropical fish or sea turtles – instead you’ll find fascinating creatures from around the coasts of the UK, such as octopus, lobsters, seahorses, cuttlefish and small British catsharks! You’ll also learn about British marine habitats and the research and conservation work which is helping to save them.

Opening times
We are open every day including bank holidays:
Mon-Sun 10am-4.45pm (last entry), cafe opens at 9.30am with hot food served until 4pm.
SPECIAL OFFER! Due to the major renovations on one of our larger tanks, we're doing a special offer this spring... If you visit us before the end of April 2018, be sure to hold on to your ticket as it'll entitle you to a 25% discount on another visit before the end of May 2018! We're expecting our conger eel tank to be fully back up and running by then so you can come see it with its usual residents! Just be sure to bring your original ticket in before 1/6/2018 to claim your discount!
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.
During the winter months we are open for group bookings.
