Cadair Berwyn and Moel Sych from Pistyll Rhaeadr

The walk starts from the car park at Tan-y-pistyll, at the foot of Pistyll Rhaeadr. After a look at the fall, take the path east and then north up the valley of the Nant y Llyn to Llyn Lluncaws, a small lake under the cliffs. From the lake a path climbs steeply up the ridge on its left-hand side to the edge of the summit plateau and turns right to the rocky top of Cadair Berwyn, 832 m, the highest point of the range. Return along the edge and continue south-west over Moel Sych, 827 m, then down the long grassy ridge of Trum Felen to the top of the waterfall, where a steep path drops through the trees to the car park.

It is 7.4 km with 554 m of ascent; allow about 4 hours. The grade is Moderate.

These are remote hills with faint paths in places, and they need navigation skill: take a map and compass. The Berwyn is boggy. The edge above the lake has steep drops, and the last descent beside the fall is very steep and can be slippery. There is no phone signal to rely on.

The car park at the falls charges, and there is a café; a little free parking lies on the road below. The lane from Llanrhaeadr-ym-Mochnant is four miles of single track. There is no public transport.
