Glyder Fawr: A Giant Among the Rocks
Glyder Fawr is the highest peak in the Glyderau range, and one of the most dramatic. With its vast rocky summit, jagged outcrops, and steep approaches, it feels like something from another world. Whether you’re scrambling up from Devil’s Kitchen or crossing from Glyder Fach, this mountain offers a wild and unforgettable experience. At 1,001 metres, it’s one of Snowdonia’s few peaks that reach above 1,000m, and the views from the top are nothing short of breathtaking.
A Moonlike Summit Above the Clouds
Glyder Fawr is known for its vast, boulder-strewn plateau and sweeping views across Snowdonia. From the top, you can see across the Ogwen Valley to Tryfan, over to Snowdon, and even out to the coast. The summit area is rugged and exposed, windswept in winter and sun-blasted in summer.
This is a mountain that feels truly wild. The ascent is challenging, whichever way you approach it, with steep scree slopes and long ridgelines. But the reward is a summit that feels like you’ve stepped onto another planet.
