About this site
Puffin Island lies off the eastern tip of Anglesey in north Wales, at the entrance to the Menai Strait, separated from the mainland by a narrow tidal channel. Diving here reaches a maximum depth of around 10 metres and is considered suitable for beginners. Divers have reported mackerel around the island, and current and changeable wave states have also been noted as hazards worth checking conditions for before entering the water.
