Hiking

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.

Running

Pen Y Gadair Fawr has a big cairn on its summit at 800m. It's a subsidiary peak of Waun Fach but probably offers better views standing at the head of the Grwyne Fechan valley. Normally run as part of the excellent Waun Fach horseshoe from either Llanbedr or Crickhowell.
