Cemlyn Bay and lagoon, Nature reserve and lagoon on the northern coast of Anglesey, Wales.
The lagoon features a shingle ridge named Esgair Gemlyn that separates the brackish water body from Cemlyn Bay's coastal waters.
The Cemlyn Nature Reserve, established in 1971, encompasses 25.2 hectares of protected coastal environment owned by the National Trust.
The site functions as a research center where scientists study marine ecosystems and document the behaviors of numerous bird species.
Visitors can access designated walking paths around the lagoon while maintaining distance from protected nesting areas during breeding season.
The lagoon hosts the sole breeding colony of Sandwich terns in Wales, with approximately 1,500 pairs nesting in this location.
