We walked miles. Up to the waterfall on Gillies trail, followed the path up onto the rocky and then to the trig point on Twyn Brynbychan, above the cynnon valleys. Enjoyed a breather on top, before trekking around the back forestry where you can see Aberfan and Merthyr Vale and headed over to the bronze age sight before descending down to Cwmaman and back to the car.
