Cemlyn Nature Reserve - Discover Spectacular Seabird Colonies, Coastal Wildlife and Scenic Walks on Anglesey

Cemlyn Nature Reserve is a beautiful coastal wildlife sanctuary situated near Cemaes on the northern coast of the Isle of Anglesey in North Wales. Managed by the North Wales Wildlife Trust, this 25-hectare nature reserve is renowned for its spectacular seabird colonies, distinctive shingle beach and peaceful coastal scenery.

One of the reserve's most remarkable features is Esgair Cemlyn, a naturally formed shingle ridge that separates the Irish Sea from a shallow coastal lagoon. This unusual landscape provides important habitats for birds, marine life and specialist coastal plants, making Cemlyn one of Anglesey's most significant wildlife destinations.

Cemlyn is particularly famous for its breeding colonies of Sandwich, common and Arctic terns. Between May and July, thousands of seabirds gather around the lagoon, creating an extraordinary wildlife spectacle. The reserve is home to the only nesting colony of Sandwich terns in Wales.

Birdwatching opportunities continue throughout the year, with wading birds and wildfowl visiting during autumn and winter. Visitors may also spot grey seals and occasionally bottlenose dolphins in the surrounding coastal waters.

The reserve's diverse habitats support a variety of plants and wildlife, including sea kale, sea campion, yellow horned-poppy and butterflies. Walking routes provide opportunities to explore the shingle shoreline, surrounding grasslands and nearby headlands while enjoying beautiful views across the Irish Sea.

Cemlyn Nature Reserve is free to visit and open throughout the year. Off-road parking is available near the main viewing areas, including the eastern beach car park and the western Bryn Aber car park, which is closest to the seasonal wildlife warden's viewpoint.

Visitors should be aware that walking along the shingle ridge can be strenuous because of the steep, loose stones. The ridge is unsuitable for wheelchairs and pushchairs, although easier walking opportunities are available around the nearby headland.

During the seabird breeding season, generally from late April until August, visitors must follow wildlife protection signs and wardens' instructions. Walking should be restricted to the seaward side of the shingle ridge to avoid disturbing nesting birds.

Dogs are permitted but must be kept on a lead throughout the reserve. Visitors should also avoid disturbing wildlife, respect protected habitats and wear suitable footwear for the uneven coastal terrain.

With its remarkable seabird colonies, beautiful coastal scenery and exceptional wildlife watching opportunities, Cemlyn Nature Reserve is a wonderful destination for nature lovers, photographers and visitors exploring the Isle of Anglesey.
