A beautiful example of the Anglesey fens, nestling in a shallow valley below limestone escarpments of calcareous grassland capped with acid heathland. The site is largely owned by the North Wales Wildlife Trust and run as a National Nature Reserve. Here are large stands of great fen sedge, with fringing areas of flushed mire with a rich flora and fauna, including rare stoneworts, butterwort, medicinal leeches, green-wingedd orchid, pale heath violet and a good population of adders! Access is best from the eastern end past "Arfryn" and onto the (slightly submerged) boardwalk across the fen. Appropriate footwear is required.
