The Glyderau

The panoramic Glyderau mountain range is slightly smaller than the Carneddau and stretches from Myndd Llandegai to Capel Curig. It is undoubtedly one of the most spectacular ruggedly beautiful areas of North Wales. Much of the Glyderau and Carneddau ranges are owned and cared for by the National Trust.

Highly popular with climbers and walkers, five of its peaks surpass 3,000 feet. The superb mountain scenery attracts over half a million visitors a year. The Dinorwig Power Station is housed within the range.

The Glyderau are a fairly rocky range , with some grassy and boggy ground towards the village of Capel Curig. The landscape was shaped by glaciers during the last Ice Age around 10,000 years ago and is regarded as one of the finest examples of a glaciated land form in Britain. According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Gludair", meaning a heap of stones.


Cwm Idwal, on the northern slopes of the range was the first National Nature Reserve in Wales, a superb, rugged bowl, gouged out by ice, with a glacial lake at the bottom. Above the cwm towers the the cliffs known as the Devil's Kitchen, or Twill Du, in which can be seen the base of the great rock fold of the Snowdonia syncline.

SnowdoniaThe Glyderau

The rocky crags and crevices of the Glyderau are home to a variety of wildlife. The vegetation in the area includes heather and artic alpine plants and has evolved over the last 500 years as a result of upland farming.

The volcanic rocks provide arctic-alpine plants with the nutrients they require, and some of the artic-alpine plants in the area are relics of the Ice Age and thrive in cold conditions. Moss campion, mountain avens, Welsh poppy, alpine lady's mantle, Snowdon Lily and purple saxifrage can all be seen.
