Y Llethr and Diffwys from Cors Y Gedol (SC)

Ascent (Feet): 2600

Starting at the car park at the head of Ffordd Gors in Dyffryn, we walk up the valley beneath Moelfre before ascending to Y Llethr. Then we have five miles of spectacular ridge walking via Diffwys before descending back to the valley and returning to the start point.
