Our Ronnie beat me to it. For any readers information, Ronnie is a phenomenal peak bagger, and is literally hiking everything in the UK that has an uphill slope. I will join him on the rounds of all the 100m prominent peaks of the UK. Y Domen Fawr is one of those peaks. Note: Y Domen Fawr, literally means a big heap or mound.

Pretty easy hike up, sadly was a cloudy day when I went so missed the views. No steep ledges and not too high at all, so good if it is windy.
