Cemlyn is one of NWWT's star reserves and regarded by the Anglesey County Council as the "jewel in the crown" of its Area of Outstanding Natural Beauty.

It is valued for both its scenic qualities and its unique range of wildlife and is as popular with general visitors as it is with birdwatchers and naturalists. It includes a large lagoon, separated from the sea by a spectacular, naturally-created shingle ridge.

During the summer months it is home to one of the most important tern colonies in the UK, and Wales’ only colony of Sandwich Terns.

In addition to being a Wildlife Trust Reserve, Cemlyn is also protected under European and UK law as a Special Protection Area, Special Area of Conservation and a Site of Special Scientific Interest.

Cemlyn’s international importance for breeding terns is recognised by its inclusion within the scope of the Roseate Tern LIFE Project. Under this EU funded project and in partnership with the RSPB and BirdWatch Ireland, NWWT will aim to boost the fortunes of Roseate Terns and provide suitable conditions for their return to Cemlyn and to Wales. You can read more about this exciting project here.

Cemlyn offers some great winter bird watching opportunities but if you are heading out there bear in mind that approach roads are subject to road closures. This is part of the plans to improve Nanner Road (the one that goes past the Jam Factory) and is linked to proposals for Wylfa Newydd Power Station.
