A high crag in scenic and isolated situation. It is a local beauty spot, so expect public attention.
Pych is a possible contraction of Pump Ychen (Five Oxen). "Apparently someone in the distant past had the rights to graze five oxen on the land. Pen means top or head. So all together it means 'top of the land on which five oxen graze". 
The left side of the wall looks as though it is going to fall down soon, but hasn't yet. The centre of the wall contains a BRILLIANT Fr. 6c+ ***, which would not be out of place a top Spanish crag. The right hand side contains steeper and shorter routes on nicely rounded sandstone.
Seepage can be a problem on the black streaks off season.
The right hand side stays in shade until 12.30 Summertime.
Look on a map and using the route most appropriate go to Treherbet in Rhondda Fawr, then head towards Blaen Cwm until horseshoe signs lead to Pen Pych Forestry Car Park. From the main car park, follow the obvious wide gravel track, zig zagging gently uphill, and then a stone stepped path for 25 minutes uphill towards the waterfall.
