Glyder Fawr

Glyder Fawr stands in Snowdonia, Wales, as the highest peak of the Glyderau range at just over 1,000 metres. The mountain rises above the Llanberis Pass and the Nant Peris valley, separated from Snowdon by these natural features. Its name comes from the Welsh word for a heap of stones, and the range formed about five hundred million years ago when land masses collided. Wind, water, frost and glaciers have shaped the mountains over millennia, leaving behind boulder fields and screes. The most recent ice age ended about ten thousand years ago, carving out Cwm Idwal and Llyn Idwal. The mountain attracts walkers and scramblers with several routes to the summit. One starts at Ogwen Cottage beside Llyn Idwal and follows the shore past the Rhiwiau Caws rock climbing crag. Another begins at Pen-y-Pass to the south, while a third follows the ridge from Glyder Fach to the east. A popular circuit links Tryfan, Glyder Fach and Glyder Fawr, taking six or seven hours to complete. The National Trust has managed the Glyderau since 1951, maintaining footpaths and drystone walls across 7,000 hectares of common land. Visitors find dramatic views from the summit over surrounding peaks and valleys. The path from Ogwen Cottage climbs steep scree to reach a small lake called Llyn Y Cŵn before ascending the western shoulder. The ridge between Glyder Fawr and Glyder Fach offers easier walking despite shattered stone near the other summit. The landscape shows the power of ancient glaciers, with moraines and boulder fields marking their retreat. The National Trust’s care keeps the footpaths clear and the drystone walls standing, preserving the wild beauty of the range.
