I had difficulty sleeping on the night before this walk because it was too warm and no breeze was blowing through my tent so I didn’t get much sleep for the start of the toughest and most demanding section of Cambrian Way. Stage six starts in the town of Crickhowell, but to reduce the length of this stage I had started it the afternoon before and walked for about four miles to a wild camp in Waun Ddu. In the morning, I set off through the thick bracken that surrounded the bog and brought me to a farmer’s track a short distance away from a road. My Cicerone guidebook recommends avoiding the fast road by following a track that parallels the road, however at this time of the year it was choked with bracken which made the walking difficult and later I began to climb above the crags of Craig y Castell even though the guidebook recommends descending to the road at that point. I was forced to walk across the top of the crags until I was at the far end where I battled through thick bracken down to the road. It was still very warm and humid with weather forecasts promising the hottest day of the year in Britain, although maybe not in the Bannau Brycheiniog National Park as the weather was initially very changeable with fleeting sunshine and attempts at rain, though for most of the morning it was just overcast. I was not looking forward to the promised hot weather reaching Wales as that would make an already strenuous walk even more difficult.
At the end of the road I took to a track that led me out onto the open moor and with the earlier sunshine gone and bleak, open moorland before me under overcast skies I put my trust in the clear path that led me to an trig point and later to Ogof Fawr, a cave used by the Chartist movement in the nineteenth century. Soon after the cave I should have turned off the track as it curved to the south, but I missed the faint path and by the time I realised it was too late to turn back so I turned north crossing the pathless heather moorland until I reached the route of the Cambrian Way which was almost non-existent on the ground and brought me to a quarry access road. A track branched off the road and took me around the Cwar yr Hendre limestone quarry soon providing me with misty views into the quiet valley of Dyffryn Crawnan. At a waterfall I crossed the stream and walked along a terraced path with views down the valley until I eventually realised I was going the wrong way and retraced my steps back to the bridge to follow the stream up past a distressing array of industrial waste. Plastics and tyres littered the ground on the edge of the quarry until I finally moved onto open moorland just as the mist dropped and the weather deteriorated so with no path navigation was an interesting challenge.
There was nothing to see in the bleak grassland until the ground steepened below Bryniau Gleision and I reached a ridge, but the ground was still no better with deep ruts left behind by off-road vehicles. However, the weather was now improving with views to my right into the valley that houses Talybont Reservoir while to my left Pontsticill Reservoir was surrounded by thick conifer plantations. I have planned to walk along this ridge on many occasions and for many years, but I don’t think I ever have, so I was devastated to find it in such a terrible state and the desolations continued beyond the trig point at the top of Pant y Creigiau with terrible scarring where the ground steepens from vehicles trying to climb the hill. At the bottom of the pass, I took to a muddy path that crossed the hillside to the stream Nant Bwrefwr where a clear, well-made path leads up the hillside. This is part of the Beacons Way, a long distance trail that I first considered doing twenty years ago, so it is great that I was now finally doing a walk that traverses the whole of the national park. As the sun broke through the clouds, a little later than it had done on the previous two days, I made my way across the open top of Waun Cerrig Llwydion to the escarpment edge above Craig Cwmoergwm. After my exertion it was great to now have a relaxing stroll with great views in all directions with the distinctive peaks of the Brecon Beacons ahead of me and arrayed in splendid sunshine.
The path above the escarpment brought me towards Fan y Big, but I stuck the route of the Cambrian Way which bypasses the top, and never seriously considered the option. From the pass, Bwlch ar y Fan, I had a choice of whether to follow the Beacons Way in bypassing the next peak, Cribyn, or to stick to the precise route of the Cambrian Way and climb Cribyn. I had decided to base my choice on the time, as recommended by the Cicerone guide, and since it wasn’t even three o’clock yet I braved the steep slopes and climbed all the way up to the top of Cribyn. The climb rewarded me with fantastic views in all directions including Twmpa, in the far distance to the east. where I had been two days ago. Now a steep descent led me to another ridiculously steep ascent that led me all the way up to the top of the highest point in the Brecon Beacons, Pen y Fan, where the stunning views continued stretching for many miles to the north. This is one of those mountains that draws the crowds so I didn’t stay for long at the top before making my way along the ridge that connects Pen y Fan with its neighbour, Corn Du, where I began my descent keeping to the escarpment edge until I reached an obelisk that commemorates the death of a five year old child. It is probable that I have not previously visited this memorial very often with the last time being in 2006, but the Cambrian Way makes the diversion so I did again before crossing the pathless grassy slopes onto the main path that led me down the hill to the Storey Arms.
This was an epic day with a lot of arduous walking across featureless moorland in grey, miserable weather until finally in the afternoon the weather cleared just as the landscape became much more interesting for a stunning traverse of the Brecon Beacons. Pen y Fan was the highest point on the Cambrian Way so far and would not be surpassed until I reached Cadair Idris more than a week later.
