Cribyn

Cribyn is a mountain in the Brecon Beacons with an elevation of 2608 feet, about 300 feet lower than the neighbouring peaks of Pen y Fan and Corn Du. It is a prominent peak in the long and impressive escarpment facing north and running roughly east–west of the central section of the Brecon Beacons.

The summit lies on a ridge stretching from Talybont Reservoir in the east, to the A470 road. The ridge line to the west connects Cribyn with the peak of Pen y Fan. To the east, the ridge line descends to Bwlch ar y Fan, a col crossed by an ancient trail sometimes known as 'The Gap Road' before ascending again to the peak of Fan y Big.
