Our View

Coedydd Maentwrog NNR, on the north side of the Vale of Ffestiniog near Maentwrog, is the largest area of ancient oak woodland in the valley. The reserve consists of Coed Llyn Mair, and a group of three adjacent woodlands; Coed Ty Coch, Coed Bronturnor and Coed Glanrafon. It includes a variety of habitats, rising from the wooded valleys onto open moorland reaching towards the slopes of Moelwyn Bach. Sometimes described as a ‘Welsh rainforest’, Coed Llyn Mair features oak woodland and a small stream. A special feature of the reserve is the animal and plant sculptures throughout the woods, which are much enjoyed by children. Because of its high rainfall and humidity, Coed Llyn Mair is home to 170 species of lichens, mosses, liverworts and ferns which cling to the rocks and trees. Animals such as the rare lesser horseshoe bat and the summer migrant, the wood warbler, can be spotted here.

About the area

Discover Gwynedd

The county of Gwynedd is home to most of the Snowdonia National Park – including the wettest spot in Britain, an arête running up to Snowdon’s summit that receives an average annual rainfall of 4,473mm. With its mighty peaks, rivers and strong Welsh heritage (it has the highest proportion of Welsh-speakers in all of Wales), it’s always been an extremely popular place to visit and live. The busiest part is around Snowdon; around 750,000 people climb, walk or ride the train to the summit each year.

Also in Gwynedd is the Llyn Peninsula, a remote part of Wales sticking 30 miles out into the Irish Sea. At the base of the peninsula is Porthmadog, a small town linked to Snowdonia by two steam railways – the Welsh Highland Railway and the Ffestiniog Railway. Other popular places are Criccieth, with a castle on its headland overlooking the beach, Pwllheli, and Abersoch and the St Tudwal Islands. Elsewhere, the peninsula is all about wildlife, tranquillity, and ancient sacred sites. Tre’r Ceiri hill fort is an Iron Age settlement set beside the coastal mountain of Yr Eifl, while Bardsey Island, at the tip of the peninsula, was the site of a fifth-century Celtic monastery.
