Caught the train to Troed-y-Rhiw and walked up from there. After leaving the village the track is stony and apparently an established motor cycle climb. Easy access to the summit once out of the wood via a track or two.Father Ted14/08/2018

Second tump of the day. Lovely walk with great views of Aberfan on the way up. We walked from Troedyrhiw, but 2/3rds of the way up we came across a very drivable road that gets you closer to the summit if you don't fancy a walk. Plateau top.Jemma Singer31/01/2016
