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.

Steady climb with lovely views of the valley. Bothy is usually busy over weekends so if you're keen to stay there without company, head up midweek outside peak season. Otherwise, embrace the spirit of what you set out to do and share an evening with a fellow bothy fan!
