This tidal lagoon and shingle ridge is a North Wales Wildlife Trust reserve, particularly for its nesting sandwich, arctic common and (occasionally) roseate terns which occupy islands in the lagoon with black heded gulls. There is a public right of way along the spectacular shingle ridge, but visitors are required to keep below the crest during the breeding season to avoid disturbance to the colony.
