About
Puffin Island (Ynys Seiriol) is a small uninhabited island off Anglesey's eastern tip, managed as a nature reserve by the Wildlife Trust of North Wales. It supports one of Wales's largest grey seal haul-out sites, plus breeding colonies of cormorants, shags, and razorbills. Boat tours from Beaumaris Pier are the only way to get close — seals are reliably spotted year-round, and nesting seabird activity peaks between April and July.

Frequently asked questions
Will I see puffins on Puffin Island?
Unfortunately no. The island's puffin colony was devastated by rats and has not recolonised. It's named for the birds that once bred there in huge numbers, but grey seals, cormorants, shags, guillemots, and razorbills are the wildlife you'll see today. For puffins on Anglesey, South Stack RSPB Reserve (April–July) is the reliable spot.
Can I land on the island?
No — Puffin Island is a closed nature reserve managed by the Wildlife Trust of North Wales. Landing is not permitted to protect the wildlife. Boat tours from Beaumaris Pier circle the island and allow close-up viewing from the water.
What's the best way to see the seals?
A boat tour from Beaumaris Pier (operators include Seacoast Safaris) brings you within viewing distance of the seal haul-out rocks. Alternatively, the headland at Penmon Point offers free shoreline viewing with binoculars — seals are often visible from the point at low tide.
