The "jewel in the crown" of Anglesey's Area of Outstanding Natural Beauty

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 Wales, including Sandwich terns. 

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.
