Puffin Island sits just beyond the eastern tip of Anglesey at the northern end of the Menai Strait. This intriguing lump of limestone provides an exciting trip with much character. There was once a huge population of puffins resident here but a rat infestation saw a dramatic reduction in numbers. A poisoning campaign against the rats has allowed the bird population on the island to recover somewhat – expect to see cormorants, shags, guillemots, razorbills, kittiwakes and fulmars, plus seals. The dramatic cliffs and caves on the north west side of the island are another highlight of the trip.
The black and white Trwyn Du lighthouse stands sentinel over the strait between the island and the Trwyn Du beach, a warning to bigger vessels of the dangers of running aground; there is also a beacon on Perch Rock which marks the south western extremity of Puffin Island.
The tidal stream in the strait can run up to 4 knots. Around the island itself the tide is less strong and can easily be paddled against.
There is a small car park close to the beach at Trwyn Du/Penmon Point. There is also a seasonal café here.
