Cemlyn Bay
Cemlyn Bay is a wild and atmospheric stretch of Anglesey’s north coast, where a sweeping shingle ridge separates the sea from a lagoon rich in wildlife. Part of the Cemlyn National Nature Reserve, it is particularly famous for its internationally important seabird colony. With rugged headlands, coastal walks and views across the Irish Sea, Cemlyn offers a wonderfully natural side of Anglesey.
