Cribyn is a mountain in the Brecon Beacons with an elevation of 795 metres.^[1]

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.[1][2]

Cribyn on a clear day is a great summit to view the dramatic summits of the Beacons and the steep drops of the northern face of Pen y Fan. It is also a quieter summit and less likely to be crowded with hillwalkers.^[2]

Geology

In common with other peaks of the Brecon Beacons, the upper slopes of Cribyn are formed from sandstones of the Brownstones Formation of the Old Red Sandstone laid down during the Devonian period. The lower slopes of the hill are formed from sandstones and mudstones of the underlying Senni Beds Formation. The rock strata tilt gently southwards. The heads of Cwm Sere and Cwm Cynwyn, to the northwest and east of Cribyn respectively, nurtured small glaciers during the last ice age. This glacial erosion resulted in the very steep northern and eastern faces which the hill possesses.
