Melfyn Parry walked up Corn Du on September 4th, 2024 [from/via/route] Started walk from car park in the Tar Fechan forest, SO 036170. Tarmac road taken up to Lower Neuadd reservoir, which is now disused, crossed a footbridge & climbed up the grassy slope to reach the ridge at a cairn SO 019182, turned right & followed easy path for about 2 miles to reach the summit of Craig Gwaun Taf. From here it is an easy walk to the top of Corn Du & then Pen y Fan (about 25mins to gain the two tops). From Pen y Fan dropped down steep path to meet Beacons Way & then steep ascent to the top of Cribyn. Turned right & followed ridge, along Cambrian Way to Bwlch ar y Fan before another steep path up to Fan y Big. From here continue along ridge to the junction of the path back to Bwlch y Fan along Craig Cwmoergwm. From this junction I dropped down the grassy slope to the Roman Road at SO 034196 & followed the path back to the car park. [with] On my own [weather] Cool breeze with sunny spells & dry. Excellent visibility. - A really nice walk, would definitely do this one again. Stunning views.
