Site Details

Cemlyn is situated on the north coast of Anglesey (SH335932). It is an area of tidal lagoon mostly cut off from the sea by a shingle ridge. The reserve is managed by the North Wales Wildlife Trust primarily for its breeding tern colony on the lagoon (which has included Roseate Tern). At the northwestern end there is a small headland owned by the National Trust and consisting of low-growing maritime vegetation and gorse scrub and a rocky coastline. The surrounding fields contain flooded pools and are worth checking out for waders. Further west are areas of wet meadow, marsh and scrub.

Additional Site Details


From Tregele on the A5025 between Cemaes and Valley, take the minor road signposted "Cemlyn". The first turning right takes you to a car park on the east side of the lagoon, or carry straight on and take the next right for the car park on the west side. From the west car park there is also a path leading to the headland and along the shore.


Wardens are present in summer. To view the tern colony, walk along the shingle ridge, keeping well below the line of white posts, then move up carefully at the green posts, taking care to avoid disturbing the birds. No restrictions except on lagoon side of ridge during breeding season.


Parking at both east and west ends of the lagoon. No charge.


Display boards and bird log (breeding season only).
