999m - 3278ft
Glyder Fawr is a mountain in Snowdonia, North Wales, the highest in the Glyderau. It measures in just short of the magic 1000m mark at 999m (3278ft).
It lies on the ridge between Glyder Fach and Y Garn, and has views to the north, across the Ogwen Valley, of Pen yr Ole Wen and the Carneddau, and views south to the Snowdon Horseshoe. The summit is very rocky, making progress slow. Routes to the summit lead from Ogwen Cottage on the shores of the lake Llyn Idwal to the north, from Pen-y-Pass to the south, and along the Glyder ridge to the east and west, leading to Y Garn and Glyder Fach.
The summit marks the boundary of Gwynedd and Conwy County Borough.
According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Gludair", meaning a heap of stones.
