Crib Goch is a knife-edged arête in the Snowdonia National Park in Gwynedd, Wales. The highest point on the arête is 923 m above sea level. A path leads over the arête and three rock-pinnacles to a grassy col at Bwlch Coch. This first part of the ridge is very exposed and climbing it should not be attempted in high wind or by the inexperienced. Moreover, on fine days the ridge may be very busy and queues can form.
From the col the ridge rises again, joining the main Snowdon ridge via the sister peak Garnedd Ugain in the west. Here the path meets the Pyg track (marked by a large standing stone) (which descends down to Pen-y-Pass car park), before the final climb to Snowdon summit.. To the south of the arête lies the lakes of Glaslyn and Llyn Llydaw. To the north is the Llanberis Pass.
Crib Goch is classed as a Welsh 3000er. It is also often climbed as the first part of the Snowdon Horseshoe, which goes on over Garnedd Ugain, Snowdon and Y Lliwedd, before returning to Pen-y-Pass.
