Birdwatching in Anglesey

By Does Your Duck Quack · Planning updated 27 October 2026

Anglesey offers seabird cliffs at South Stack, wetland watching at Cors Ddyga, freshwater lakes at Valley Wetlands and the dunes and forest of Newborough. South Stack combines maritime heath, farmland and sea cliffs, with Guillemot, Razorbill and Puffin among the breeding seabirds and Chough interest through the year. Cors Ddyga’s reedbeds, wet grassland, pools and ditches give a different setting for Bitterns, breeding waders and winter wildfowl. Valley Wetlands adds reed-fringed freshwater lakes, with Tufted Duck, Pochard and Shoveler among its birds. Newborough provides a broader habitat mix of dunes, forest, freshwater pools and estuary. On the north coast, Cemlyn pairs a lagoon with a shingle ridge and a breeding tern colony. Its loose shingle is strenuous underfoot; the more distant roadside view near the western car park is a separate option described by the operator. These named places give Anglesey cliff, lagoon, marsh and woodland contrasts, each with its own public route rather than a single island-wide circuit.
