Landscape - Cemlyn Bay

Cemlyn’s enchanting curved bay is unique with its shingle ridge known as Esgair Cemlyn dividing the open sea from a saline coastal lagoon - considered to be the best example of its type in Wales. The Bay is situated approximately 3 miles from Cemaes on the north west coast of Anglesey.  It is flanked by the headlands of Trwyn Cemlyn and Cerrig Brith.

The bay and surrounding land forms part of the Cemlyn Estate which is owned by the National Trust.  Since 1971 the North Wales Wildlife Trust has leased the lagoon area which they manage as a nature reserve. In the summer months, the lagoon provides a sanctuary for its famous tern colony which is deemed nationally important as it is home to the only breeding colony of sandwich terns in Wales.  The lagoon was created in the 1930s by the wealthy Captain Vivian Hewitt.  He built a dam and a weir at Cemlyn, changing the saltmarsh area into the lagoon which can be seen at the site today.  He had a keen interest in birds, and lived at Bryn Aber, which is  situated on the western side of the bay.  Captain Hewitt was the first person to fly from Wales to Ireland, but his achievements were overshadowed by the Titanic disaster of 1912.  The Anglesey Coastal Path traverses the bay and the National Trust have a series of short circular walks taking in the bay and the picturesque surrounding area.  The wonderful views can be appreciated from the car parks from where it is also possible to witness the tern breeding spectacle over the summer months.
