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.

If you’re into ancient history, seeing an old cairn on top of an Iron Age hillfort is very exciting!

The roads leading to the Sugar Loaf mountain are all very narrow, 1 car width. You may meet oncoming traffic and need to reverse 100m or more to a passing point. Do not be put off! The car park is small but does have an overflow area 200m before you get to it. The walk leads you naturally into a steep decline into a valley, possibly 130m lower. It doesn’t sound much but the climb from that position is significantly harder. My advice would be to walk around this valley and follow the alternate path. Namely when you walk from the car park do not aim for the top but go further to the left. So much easier to do. The views are stunning and totally worth the effort. Enjoy komooters😀
