Moel Penderyn 371m ⛰️ Moel Penderyn is on the edge of Penderyn village, located in the Brecon Beacons National Park county borough of Rhondda Cynon Taff, South Wales. It also appeared to be named as 'Y Foel Penderyn' on older maps. With a summit elevation of only 371m in height, Moel Penderyn is marked by a bright, vivid, beautiful Dragonised trig point!!❤️👌

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.
