Pen y Gadair Fawr stood at an impressive height of 800 metres, and is an subsidiary summit of the highest peak within the Black Mountains … and that is the summit that is of Waun Fach-(811m). Pen y Gadair Fawr is the second highest peak that’s located in the Black Mountains in south-eastern Wales. Marked by a medium-sized cairn, it is a much more distinguished top than its parent 1.5 km to the northwest. Its 658 metres high top Pen Twyn Mawr is about 2 km to the southeast.

Nice path to summit with some large stepping stones depending on which way you go.

A fine viewpoint, but the cairn has gone (was getting a bit big).

In terms of height, Pen y Gadair Fawr plays second fiddle only to Waun Fach as the Black Mountains' second highest summit. However, where Waun Fach's top is broad and relatively uninspiring, Pen y Gadair Fawr's is a little more like a peak in character. The summit is at a junction of paths: head east for Chwarel y Fan and the Mynydd Du Forest, venture south to Pen Twyn Mawr, or stride northeast to Waun Fach.

Great walk that's pretty accessible for most people to achieve, challenging but doable! The route I took incorporated Lord Hereford's Knob. I published it on Komoot here: https://www.komoot.com/tour/1576268965 And on my blog here (with extra commentary for my own entertainment!): https://weekendwalk.co.uk/route/hay-bluff-walk/

The flat summit of Hay Bluff which is marked by a beautiful welsh dragon trig pillar at a height of 677 metres (2,221 ft) overlooks the middle Wye Valley and the book town of Hay-on-Wye.
