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.

Be aware that if you come down to the dam on the lake you can't escape through the valley, there's a gate on both of these minor roads coming down off the dam with some very threatening signs. You have to take on one of the bastard ramps, east or west doesn't matter, they're both brutal, though I can imagine eastward is worse.

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.
