Cors Goch National Nature Reserve

This superb example of the rich fens of eastern Anglesey was the first North Wales Naturalists' Trust (now North Wales Wildlife Trust) reserve, in 1967. Now managed as a NNR by the NWWT it comprises a discrete vally mire within this limestone landscape. There are two residual areas of open water, including the deep Llyn Cadarn, and areas of acid heath on outcrops of millstone grit, but the chief feature of the site is the large area of fen - characterised by rustling stands of common reed, great fen sedge, blunt flowered rush and black bog rush. Amidst this initially uninspiring sounding collection of plants is a profusion of orchids, insectivorous plants, rare giant algae or stoneworts, dazzling dragonflies, grasshopper warblers, bloodsucking medicinal leeches ..... and whatever else you can find when you look closely.

There is a public right of way along the southern boundary of the fen. A boardwalk has been constructed to enable people to enter the dense fen areas, though in parts it is floating over deep soft peat so Wellington boots may be advisable at times! Access is best from the eastern end, where roadside parking is available with care.
