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.

Mynydd Bedwellte is a nice little hill in the Rhymney Valley that has a prominence of over a 100 metres. It has the obligatory trig point, and there is also a nice bench seat here too. The views down the Rhymney Valley are really nice from here, especially on a nice day as it was today.
