## Sea Zoo — Anglesey’s Underwater World
[Anglesey Sea Zoo](https://www.angleseyseazoo.co.uk) in Brynsiencyn is one of the island’s most popular family attractions, and deservedly so. It’s Wales’ largest marine aquarium, with lobsters, rays, seahorses, sharks, and a giant spider crab that never fails to impress younger visitors. Allow at least two hours. The café and gift shop are good, and the outdoor areas work well on a warm day.
Great for: ages 3 and up. **Anglesey self catering** guests staying in the southwest of the island are ideally placed for a visit.

## Beaumaris Castle
A UNESCO World Heritage Site and one of the finest concentric castles in the world. [Beaumaris
Castle](https://cadw.gov.wales/visit/places-to-visit/beaumaris-castle)
is compact enough to hold younger children’s attention while being genuinely interesting for adults. The town of Beaumaris itself is lovely — excellent ice cream, good independent shops, and a café culture that makes it easy to spend a full morning here.
Great for: all ages. Older children with an interest in history will particularly enjoy it.

## Zip World Fforest (Betws-y-Coed)
Just across the Menai Strait and worth the short drive, [Zip World
Fforest](https://www.zipworld.co.uk/location/fforest/) offers family-friendly zip lining, tree surfing, and the Treetop Challenge adventure course. It’s an incredible setting in the heart of Snowdonia — thrilling without being scary for younger children. Booking in advance is essential in peak season.
Great for: ages 5 and up for most activities.

## Pili Palas Nature World
[Pili Palas](https://www.pilipalas.co.uk) near Llangefni is a brilliant wet weather option. A tropical butterfly house, meerkats, reptiles, and a soft play area make it a reliable family hit whatever the weather. It’s genuinely impressive for a smaller attraction and the kids tend to stay far longer than you expect.
Great for: ages 2–10 especially. A smart choice when rain interrupts beach plans at your **anglesey cottages** base.

## Llanddwyn Island and Newborough Beach
This combination is hard to beat for a family day out. Pack a picnic, walk through Newborough Forest, emerge onto one of the finest beaches in Wales, and continue to Llanddwyn Island at low tide. There’s a lighthouse, ruined medieval chapel, and views across to the Llŷn Peninsula. It’s free, it’s beautiful, and children love the sense of adventure. Check tide times at

before you go.
Great for: all ages. Dogs welcome too.

Cymru](https://www.sustrans.org.uk/find-a-route-on-the-national-cycle-network/lon-las-cymru/)
passes through the island and can be ridden in sections suitable for children. Several local hire companies offer bikes including child seats and tagalongs — making it accessible for families staying in **anglesey self catering** accommodation without their own bikes.
