The Cambrian Way is an iconic long-distance footpath that runs 298 miles (480 km) from Cardiff in the south to Conwy in the north. That distance comes with a challenging 22,500m (73,700ft) of height gain. This tough trail passes through some of the most spectacular and beautiful scenery in Wales. It can also be very remote, and in the north you will hit rugged terrain that will include high ridges and challenging mountains. You can do it in more attainable one-day sections, or you can be a purist and do it in a gruelling, continuous three-week hiking odyssey. Here on the southern flanks of the Sugarloaf, the terrain might be more sedate, but it is as equally as beautiful. The hike up from Abergavenny on this Cambrian Way section has good views of the Sugarloaf in front, across to the Blorenge in the south, and Skirrid Mawr to the east. Not for nothing was the Sugarloaf included in the Trail magazine’s Top 100 Britain's Greatest Mountains list.

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.

A small summit above Risca. Known locally as the "Twmp" (the hump), the pimple or the nipple, due to the shape of the mound on the summit.

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.
