Glyder Fawr

Featured photo of Glyder Fawr

The fifth highest mountain in Wales, Glyder Fawr, is situated on the east to west ridge of mountains known as the Glyderau of which it is the highest point. The ridge is characterised by rocky cwms or cirques and airy ridges overlooking the Ogwen Valley to the north and smoother less precipitous outlines dropping to the south. The slopes above the Llanberis Pass however are a vast sweep of boulders which drop right to the roadside.

The easiest ascent route is from Pen y Pass and is a mainly grassy path which rises without any difficulty to the summit with no hint of the bouldery chaos dropping to the valley below. This route is usually done as a circular, traversing to Glyder Fach and descending to Pen y Gwryd. There are short scrambles and very rough sections en route to Glyder Fach. The mountain presents its most impressive face to the north overlooking the atmospheric tarn of Llyn Idwal. Here the Idwal slabs provide many rock climbing routes and the Cribin Ridge, an exiting but safe walking route to the peak. There is a path down through the cliffs below the dark cleft of the Devil's Kitchen or traverse to Y garn west of Glyder Fawr or Glyder Fach to the east.

    Glorious day, did it from Glyder Fach then went on over Y Garn and Foel Goch. Hard to decide which of the two tors is the highest, though I've heard the south one is fractionally higher

    Try a rock route starting with "Hope" on the shores of Cwm Idwal - continue with "Lazarus" and finally "The Arete" high above the tarn. Great mountain with good rock.

    Quick stroll from Pen y Pass to the summit of Glyder Fawr between lunch and tea. Left @ 12.00 and reached summit @ 13.30.A crisp cloudless day, with the ground and streams frozen.

    Started from Gwynedd and ran the ridge on the Tryfan side -- cutting off the walking path after the sheep gate. The sun came out and we could see up the valley to Bangor. Beautiful.
