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.

The Beautiful Cefn Cil Sanws is a 'hill' in the Brecon Beacons National Park within the county borough of Merthyr Tydfil in south Wales. The summit at 460m above sea level is crowned by a trig point. The steep cliffs of Darren Fawr and Darren Fach defend its western side which drops down into Cwm Taf. A major limestone quarry is worked on the southeastern side of the hill. An unexpected feature at this altitude is Merthyr Tydfil Golf Course which extends high onto the eastern and southern slopes of the hill. The hill is composed of a layer cake of rocks of Carboniferous age all tilted moderately to the south. The summit is formed from Carboniferous Limestone whilst outcrops of Twrch Sandstone formerly known as the Basal Grit of the Millstone can be seen to the north and on its steep western flanks. The latter show evidence of glacial striations suggesting that the hill was over-ridden by ice moving southwards from the central Beacons during the ice ages.

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.
