This is the col between Corn Du and Craig Gwaun Taf. Not only is it a fine viewpoint, but it is also the parting of the ways. Turn right at the marker stone you will follow the crowds down to the Storey Arms, turn left to Craig Gwaun Taf and you arfe likely to have the airy path all to yourself.

This is the ridge route to Pen y Fan from the north. A fine route that steepens sharply near the top.

Cribyn is the smallest of the Brecon's 'big Three, but it is a shapely top and should be included in any climb up here.

When coming off the mountain to go down towards the car park it’s quite a steep scramble and can be slippery

Fantastic views from the top. Just take your time and don’t burn those legs out too soon.

Completed on a cold, icy morning. Even though sun was on this section - there were some very slippy areas, so proceed with caution. Otherwise generally good climb
