Anglesey Sea Zoo is an independent aquarium and marine conservation centre on the south coast of Anglesey, near Brynsiencyn. Over 40 tanks show native British sea life, including octopus, lobsters, seahorses, conger eels and jellyfish. Highlights include the No Bone Zone for invertebrates, a wolf fish lair, a real crashing wave, a shipwreck and a kelp forest full of big fish.
Tip: No need to book ahead, as tickets are bought on the door. Standard and family tickets stay valid for 6 days after the day of purchase, so you can return for free in that time.
