Starting from the Black Hill CP, we walked down to the Olchon valley, noting that the right of way had been diverted to the north of Black Hill Farm. A short walk along the lanes before heading up to meet the ODP at the ‘pile of stones’ – one of many which seem to have proliferated along the path to the north (being cleared for a new 'highway'?). Up to Hay Bluff and straight on down the north side before skirting round the hill, gently descending, then walking below the multiple rivulets on the face of the hill from which the feeder streams converge to form the source of the Monnow – the focus point of our walk. It was an extremely worthwhile destination, with small waterfalls, pools, grassy carpets and masses of late-flowering hawthorn – delightful. From there we headed SE along the foot of the hill, enjoying great weather, red kites soaring close by, more splendid hawthorn blossom and a route that was new to all of us. Then, cutting back, we ascended to the Black Hill ridge and the along the magnificent route down the Cat’s Back (author’s favourite!). Congratulations to Terry for a well-researched route (and parking, when it was thought the road from Longtown was too rough to use - now resurfaced in the worst parts.).

Starting from the Storey Arms, we headed west on the Cambrian Way (not much to see by way of a path on the ground) crossing over several streams which feed into the Ystrafellte Reservoir. The first of these was slightly challenging to cross, resulting in a couple of instances of ankle-dipping – the first of many during the day. It is a long time since we walked so consistently over wet and waterlogged ground – the result of several days of heavy rain. Having crossed Bryn Melyn, we dropped down to Maen Llia a 3.8m standing stone thought to date from Neolithic times. A few km of tarmac followed until we crossed the river at the Blaen Llia CP, noticing the greying skies and lowering cloud over Fan Nedd. As we approached the top of Fan Llia, the light drizzle started, which would last for most of the return leg of the walk. We crossed our outward path to walk along the edge of Craig Cerrig Gleisiad and Craig y Fro – but unfortunately with only views into the mist, as we walked down the car park.

It is a shame that the Met Office provides forecasts which are often more pessimistic than actual. Such was the case for our CW section from Pen y Fan to Storey Arms. We walked pretty much south from the Cwm Gwdi car park, navigated a barrier of gorse bushes, then along Cefn Cwm Llwch and up the nose of Pen Y Fan – getting pretty much all of the ascent over within the first 3 miles. There were a couple of rain showers en-route, with one v. blustery, heavier shower as we covered the last few hundred meters up into a light mist. The weather improved as we walked down to the Tommy Jones memorial and Storey Arms – accompanied by a profusion of skylarks singing away. For the return route we followed the undemanding Taff Trail (sans waterproofs) and lanes back to the car, pleased to have been guided by the rainfall radar forecast, which generally gives a better guide to the day’s weather.

Starting from the upper Blaen –y-glyn CP, we headed up towards Craig y Fan Ddu, picked up the Cambrian Way, then followed the route across the glacier-smoothed sandstone tops to Fan y Big. Then down into the bwlch, up to Cribyn, Pen y Fan and Corn Ddu. Magnificent views continued as we walked south along Graig Fan Ddu to the trig, then down the steep descent to the Taff Trail, where David informed us about a tunnel at the head of the Brecon Mountain Railway. Despite our many visits to the area, no one else was aware of this tunnel – so some exploring needed on a future visit. We returned along the road to the cars, with cuckoos calling in the woods. A lovely day with light cloud, warm when sheltered, but a cool NE wind at times.
-
Leaving Portishead, we walked through Weston Big Wood up to the Iron Age hill fort at Cadbury Camp. From there, we made our way to Clevedon and joined the coastal path for the trek back to the cars. It was a beautiful sunny day, and we were treated to some excellent views across the Bristol Channel.
-
The next section of our Cambrian Way walk started from the Upper Blaen-y-glyn car park, above Talybont reservoir. The first task was to complete the short CW link from the Pontsticill road to the path heading north to Craig y Fan Ddu. This was to avoid having to do it on the next CW walk. We headed eastwards on the Taff Trail – hearing our first cuckoo of the spring – before cutting off towards Pen Rhiw-calch and then up to the tramway, where Ceridwen pointed out the remains of an old Roman bridge. Down into the Dyffryn Crawnon valley and up Cwm Pyrgad to the Nye Bevan memorial, where we joined the CW. This section of the CW crosses the rough upland to the Pant y Creigiau trig and then down to the cars. Excellent weather with light cloud and sunshine – but not too warm.
-
Leaving the Blaen Onneu car park we rejoined CW where we left it on the last leg. Across the open moorland and up to the trig on Mynydd Llangynidr where the first rain showers came in. From there we continued to Chartist Cave, then on across more open moorland to meet the Trefil Quarry road above Darren Ddu. From there back along to Trefil taking the high route above the quarry. Into Trefil and out along the old railway track. Leaving the track we headed N on a well-marked path to Llangynydr reservoir. The rain came in persistently then. Across even more open moorland following sheep tracks N. Significant dolines apparent, one water filled. Then back to the cars, but with a horrid hailstorm just before the finish. Wonderful moorland walk with lots of weather, again showing the landscape variety of our hills.

Starting from Brynmawr, we walked along the Clydach Gorge footpath/cycleway, crossed the dual carriageway, headed up Cwm yr Hafod onto Mynydd Llangattock and up to the trig point. We continued down to Coedcae Uchaf farm, then turned east at Twyn Langwilym to head eastwards and southwards, passing the Lonely Shepherdess and descended to Blackrock, before re-crossing the A465. We climbed back up to the cycleway, headed across the hillside to Clydach to visit the old ironworks and then back up to one of the magnificent viaducts to rejoin the cycleway for our visit to walk through the Gellifelen tunnel (Note: There are two tunnels here because the Merthyr, Tredegar and Abergavenny Railway (MTAR) was doubled in 1877 to handle increased traffic flows, necessitating a second, parallel bore, to the south of the original 1862 tunnel). As the group started to relax (retracing our outward journey), the walk leader had other ideas and took us up (the steep) Cwm Nant-gam to join the Blaenavon cycle track for a short final stage back to the cars. The warmest day of the year – sunny enough to bring some shorts out – good views, but slightly hazy.
-
A further stage of the Cambrian Way. From Crickhowell we walked through Llangattock and up two sections of old tramway routes used for bring limestone-carrying wagons down to the canal. The routes are steep and in poor condition, with grooves in the stone from the ropes and cables used to control the wagons’ descent. After walking past the old limestone workings and cave entrances, we dropped down into the Craig y Cilau nature reserve and then up to the minor road, where we headed west for 2km of road walk towards the Blaen-Onneu quarry. Then northwards along the edge of the open access land, across a minor road and down a very uneven, water-scoured lane to Llwynon Farm (not to recommended as a route) and onto the Usk Valley Walk, which led us down to the canal and our return route to the car park. An overcast, but mild day – pleasant walking conditions and mainly dry underfoot.

The forecast for the day was pretty grim, with very strong winds, severe wind-chill temperatures and possible snow forecast. Rather than drive to Llanfrynach, for what might have been a curtailed walk, we decided to walk from Abergavenny. Kay had recently been on a lower-level BBPS walk and we walked a similar route - from Abergavenny, up to Home Farm, down to the vineyard and then westward under Llanwearth Breast to the woods of Y Graig (click for more info.), a steep hillside on the south side of Sugarloaf. We diverted to see the remains of a settlement which existed here in the eighteenth and nineteenth centuries, stretched out along (what were) terraced clearings on the side of the hill. We were fortunate that CADW/NRW were undertaking some remedial work on an old bakery – a lady from CADW gave us some interesting insights into the history of the settlement. We continued through the woods and returned at a higher level to Pen-y-graig farm onto open land to the top of St Mary’s Vale and returned via the Rholben. There were occasional short squally showers, with a snow shower in early afternoon; otherwise sunny intervals in the morning and rather overcast during the afternoon.
-
We headed north from Crickhowell up Cwm Cumbeth, then through the sheepfold and on to Table Mountain. From there, we walked along the eastern boundary of the open access land, dropped down to the road before Ty Croes Farm, then NW-wards over Tal Trwynau to Pen Twyn Glas where we joined the CW, to follow it back to town. Pleasing to hear the call, and have a sighting, of a yellowhammer en-route, and hearing a goshawk in the woods to the east (report courtesy of our resident ornithologist). South to our highest point at Pen Alt-mawr, where a slight deviation took us towards Pen Gloch-y-pibwr, before correcting over rough ground to the CW. The track on the top is no longer the previously rough stones, but made up with large stone blocks and stretches of aggregate. Passing to the east of table mountain (which, btw, is a far more impressive sight when viewed from high ground to the north, than elsewhere) we descended into Crickhowell. This was the best weather of the year to date – warm, sunny, little cloud and only a slight cold wind for a while on top.

20260318 Pen Twyn Glas - Cambrian Way -
We started at Pengenffordd, headed up the Dragon’s Back and rejoined the Cambrian Way just east of Mynydd Bychan. Then south to Waun Fach, along the tops to Mynydd Llysiau and finished this CW section at Pen Twyn Glas. We then dropped down the south side of Cwm Nant-y-fedw (always a lovely view) towards Waun Fach (village) and then headed north to walk up the Rhiangoll valley. This was rather muddy in parts and potentially very challenging in heavy rain as the path is eroded into an unavoidable 40cm gully, in parts. The day started chilly and at times on the top we had very cold, very strong NW winds whipping across. The wind eased as we lost height and the afternoon was pleasantly sunny, but still chilly.

The 7th stage of the group’s Cambrian Way expedition started from the Blaen-y-cwm car park, towards the top of the Grwyne Fawr valley. We headed up through the woods, over the ridge by the Blacksmith’s Anvil, then steeply down to Capel-y-ffin (on a path which seems considerably more eroded that when previously walked) for a coffee break. The community in the valley has another communications problem as the Cwmyoy to Llanthony road is closed again due to a landslip - which has removed all support from a section of the road. We ascended Darren Lwyd (with only a minor confusion regarding a left or right turn!) and continued up to Twmpa and then along the top of the escarpment. An extra 300m if CW was completed (and retraced) before we headed down the always-delightful Grwyne Fawr valley and the reservoir to the cars. We enjoyed a beautiful spring day, with sun, a few clouds, the song of many skylarks in the air and masses of frogspawn in the pools.
