Cemlyn Beach, situated on the north coast of Anglesey, is a notable destination for nature lovers and those seeking to explore the unique wildlife habitats of Wales.

Cemlyn Beach is a large stretch of shingle beach located on the north coast of Anglesey. The beach features a shingle ridge at its rear, which offers protection to an impressive saltwater lagoon. This lagoon serves as a crucial habitat for wintering birds and is a key aspect of the area's natural significance.

The lagoon, which is partly man-made, was created by Captain Vivian Hewitt, who built a dam across the outflow to further his interest in birds. The North Wales Wildlife Trust manages the reserve, which is renowned for its colony of breeding sandwich terns. The reserve's unique features and wildlife make it an essential part of the local ecosystem.

The beach, lagoon, and surrounding countryside are owned by the National Trust as part of the Cemlyn Estate. This ownership guarantees the preservation of the area, ensuring its natural beauty and wildlife habitats are protected for future generations. However, the presence of the Wylfa nuclear power station to the east is a notable feature of the surrounding landscape.

Cemlyn Bay is an ideal destination for nature lovers and walkers, offering a wide, sweeping natural beach and the opportunity to explore the Cemlyn North Wales Wildlife Trust Reserve. The area's unique combination of natural habitats and wildlife makes it a valuable resource for those interested in exploring the natural beauty of Anglesey.

Cemlyn Beach is adjacent to the Anglesey Coast Path and the Wales Coast Path.
