Our View

The Ceunant Llennyrch NNR near the village of Maentwrog is one of several woodland reserves in the Vale of Ffestiniog in Gwynedd, and runs from Trawsfynydd Lake to the River Dwyryd. The reserve’s broad expanse of woodland encloses a spectacularly steep gorge, through which the stunning Afon Prysor waterfall cascades. At one point, the river is flanked by 100ft-high cliffs, which face each other at only 35ft apart. The high humidity offered by the wooded falls creates the perfect environment for numerous damp-loving plants. The steep banks are clothed with bilberry and the delicate white flowers of wood anemones and wood sorrel in the summer. Due to the levels of humidity and shade which don’t suit vascular plants well, the flowers play a subordinate role to the abundant mosses, liverworts, ferns and lichens. Among the few exceptions that appear in some of the less rocky areas is the bright yellow common cow-wheat.

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.
