This walk covers the high points of both the Welsh Principal Areas of Merthyr Tydfil and Caerphilly.

To start the walk I parked outside the Red Cow Inn at Pontsticill and followed the road down the hill to cross over Taff Fechan (river) to meet the Taff Trail. Cross the road opposite the water treatment plant to join a footpath that leads up the hill in a north-easterly direction. The path crosses under the Brecon Mountain Railway to meet a path junction at the 350m contour line. Take a right and keep to the path now heading south-east. At the 440m contour line, approximately 1.4km into the walk, leave the path and cross open land towards the high points. This is where I found it essential to follow my GPX track as it’s easy to get lost up there.

The route to the high point roughly follows the border of Merthyr Tydfil and Powys until you reach a dry pond that marks the Merthyr / Powys / Caerphilly county tri-point. The Merthyr Common high point is to the west of the pond and Pen March to the east. There’s nothing to mark either and neither feels like an achieved summit as the ground in Powys to the north of the border is higher.

My original plan for this walk was to include the Trig Point at the summit of Cefn Yr Ystrad. It was now late in a full day of high-point bagging, getting cold and the route to the Trig Pillar was boggy. I decided to leave Cefn Yr Ystrad for another day, return to Pontsticill and rest for more high-points the next day.

This was the second of three trig-bagging walks in the Black Mountains on a spring trip to the Brecon Beacons. We were on the last day of good weather before a long stretch of rain so we picked this one based on recommendation from a friend who lives nearby.

Many people start their Sugar Loaf trip from Abergavenny and there’s lots of footpath options between the town and the summit. The approach from Llangeny is a great alternative, especially if you’re travelling there from the North or West.

From the Dragon’s Head car park, cross over the (river) Grwyne Fawr, taking a left on the road that runs parallel to the river. Take the first road on right and walk up the hill in a north-easterly direction. After ~1.25 km from the start continue along the footpath through a farm rather than keeping on the road that curves to the right. Once past the farm you’ll follow the edge of a field upwards towards a path T-junction. Take a right here heading south. This path will curve round the brow of a hill before heading north east up to the summit of Sugar Loaf.

On a clear day the views from the summit are excellent so it’s worth spending a bit of time there to take it all in. To return to the start, take the north-westerly path which curves round to the west. After 3km from the summit the path enters a farm where you’ll take a right onto the road. Soon after this take a left onto another road, another left at the end and continue to the junction where you’ll meet your earlier route up. Take a right here and retrace your steps to the bridge then the Dragons Head pub.

This was the second of three trig-bagging walks in the Black Mountains on a spring trip to the Brecon Beacons. It was my birthday and, having missed out on our normal big trip due to Covid, I wanted a special mountain. It may not be well known, a County Top or on many bucket lists, but as the highest peak in the Black Mountains, that would be enough significance for this year.

The car park next to the Dragon’s Back pub is an obvious place to start. The honesty box for the £2 charge gives warnings of tough-to-remove stickers to be stuck to windscreens if the charge is not paid. Despite the CCTV cameras above it, it’s unlikely they would know you’ve put money in there. After a year of not touching any cash I was pleasantly surprised to discover that we actually had some coins in the car.

Take the footpath that starts at the north end of the car park and follow it in a south-easterly direction for just over 3.5 km. Here you’ll reach a ridgeline with several different footpath interactions. Take the path that heads north, continuing to ascent, then curves to the east. Follow this path for approximately 2km to the summit of Waun Fach. There used to be an OS Trig Pillar here, but it’s been replaced by a low, flat stone with a metal OS roundel on it.

From the summit, take the northerly footpath, descending steadily for 1.5 km. At the path junction take the left hand path, heading south west, descending along the Dragons Back. We had very good visibility which gave us some amazing views across to the National Park to Pen y Fan and beyond. The highlight at the end of the trip is the path through the ruins of Castel Dinas. The steep ascent up to to the castle right at the end of the trip was a bit daunting though given we were low on energy at the time.

I’d been hesitant about doing this one having read and heard of tough navigation and boggy conditions at the top. The path at the summit seemed relatively new so have probably addressed the bogginess issue. I’d say that the navigation is no tougher than similar mountains in the area so you’ll be fine with the usual preparation, clothing and skills for the hills.

This was the first of three trig-bagging walks in the Black Mountains on a spring trip to the Brecon Beacons. With a short distance and relatively low elevation this made for a nice warm-up for the longer treks of the next couple of days.

The parking area just outside of the Llangorse Activity Centre is an obvious place to start. Just inside the activity centre you can find the start of a footpath heading in a south-easterly direction across a field towards the hill. The trig pillar at the summit is only 1.5km from the Activity Centre, giving you the option of a very short out-and-back. If you prefer a longer circular walk, there’s several options based on a few paths that intersect at the summit. We continued east for ~500 metres, then taking a well marked track south to the Beacons Way.

When you meet the Beacons Way, don’t follow it but take the westerly path that makes a steady descent from the hill. This path will curve round to the hill and reconnect with the path you followed at the start and back to the Activity Centre.

The cafe at Llangorse lake, a short drive from the Activity Centre, is a great place for a rest, a coffee and a cake after the walk.

In the third of three winter walks in the Vale of Ewyas we did a circular trek to the summits of Twmpa and Rhos Dirion.

From the free parking at Gospel Pass take the westerly path up to the summit of Twmpa, also called Lord Hereford’s Knob. Trig Baggers will be disappointed as there’s no pillar at the top. By continuing west for another 1.8 km you’ll reach the patriotically painted pillar at the top of Rhos Dirion. We were there on a cold but clear winter’s day and had a great view of Pen y Fan in the distance. After bagging Rho Dirion, retrace your steps down to the col between the two summits. Rather than climb back up to Twmpa, take a right to head in a south-easterly direction down the valley. Navigation is easy following a well worn path tracing the course of Nant Bwch.

The valley path turns into a farm track then a single-track road to Capel-y-ffin. Rather than stick to the road follow the path that curves round the side of the nose of the mountain half way up its elevation. On the southern-most point you’ll get a great view over Capel-y-ffin and the southern part of the Vale of Ewas.

Continue on the mountain pass as it curves anti-clockwise around the mountain. You’ll now be heading north back towards the Gospel Pass. After ~2 km the path will join the valley road which you can follow back to the car park.

In the first of three winter walks in the Vale of Ewyas we did an out-and-back trek to the North Daren Trig Pillar.

From Capel-y-ffin village centre, take the track to the right of St. Mary’s Chapel. Continue for ~1 km passing over the River Honddu, the Baptist church on the left and a farm on the right. When you reach the footpath sign for Offa’s Dyke, cross over the stile on the left of the track. From here follow the path at it climbs and zig zags up to to National Trail. The path uphill path was very obvious when we were there in winter but can be obscured by bracken in the summer.

A cairn and a stone sign marks the junction of the uphill path and Offa’s Dyke. Turn right (south-east) onto the National Trail and continue for ~1.6 km until you reach the Trig Pillar. For the return trip, retrace your steps back to the bottom of the hill where the path meets the track. Here you can take a right and follow the track back to Capel-y-ffin or take a left then a footpath shortly on the right. Here you can follow a path across a field, over a wooden bridge and onto the valley road. Take a right when you get to the road to return to Capel-y-ffin.

If I had known that I’d be returning to the Ewyas valley many times in the future I probably wouldn’t have attempted this on on such a rainy day. As it happened we were on the last day of a long weekend in the Brecon Beacons and I was eager to bag this one.

Although Black Mountain is the high point of Herefordshire, an English County, much of the walk is in Wales. The obvious starting point is the car park at the top of Gospel Pass. From here there’s a well trodden path up the side of the valley to the Hay Bluff Trig Pillar. From the pillar, take the south-easterly path to join Offa’s Dyke. Continue for ~1.2k until you get to the high point. There’s nothing here except for a small group of stones. As visibility was very poor and it was raining a lot, we quickly retraced our steps back to the parking spot.

In the following years a good friend of ours would move to the valley and we have done a lot more walks near there. With better weather and more time I would plan a different walk that includes both Twmpa and Black Mountain.

Cycling the NCN route 8, the Welsh End to End, was my alternative Stag Do. Although I had a more traditional one, my interests at the time were returning to the outdoors and this would end up being more memorable. It was a four day, three person adventure through the the heart of Wales.

The route is also know by its Welsh name, Lôn Las Cymru, which means Wales' Blue Lane. I'd only heard of this name in the last few years so I assume it adopted it since our trip. Whatever the name, it's a great North-South end to end as an alternative to, or warm up for the much longer LEJOG.

Unlike LEJOG the far ends of the route are easily accessible by train. We were travelling up from South East England and took a train from London Euston to Crewe then the North Wales Coast line to Holyhead. The return trip from Cardiff is even more straightforward with many options for trains heading east into England.

Once a busy port town for ferries to Dublin, Holyhead has lost its way in recent years. There's not much reason to stop in town now if you're taking the ferry. We were just staying one night but quickly ran out of things to do. It was a few years before I'd started my UK County Top obsession. If I'd known at the time it would have been a short cycle to Holyhead Mountain to bag the highest point in Anglesea. I returned a few years later to claim it on a tour of the North Wales County Tops.

After a good night's sleep we set off early to find the start of the route and make our way south. Splitting the trip into 4 days gives you enough time to see the country and get enough miles in. It also nice splits into 4 distinctly themed days.

Day 1 is beautiful, cutting through the heart of Anglesea, over the Menai Bridge and across the top of the Llyn Peninular. By contrast, Day 2 is hilly with more dramatic scenery as you curve round the south western edge of the Snowdonia National Park. Day 3 is a gentler descent through mid-Wales through some stunning countryside often overlooked by tourists. Day 5 is the Grand Finale, tracking the Taff Trail through the Breacon Beacons National Park, through the valleys to Cardiff Bay.

For a more detailed description of the route I recommend the section in Big Rides (look out for my own Day 3 photo on page 76).

In the years before I got married the Pen y Fan, Cribyn and Fan y Big circuit was my Girlfriend Test. If it was looking serious I would "take them up the Brecons" to see if they survived. If they liked it, it was a good sign.

I did The Test on my wife, then girlfriend, in 2002. She passed it, although didn't quite make it all the way back to the car park. I remember her sitting down on a rock 100 metres from the car park and refusing to move. I went ahead and to get the car to pick her up on the way back to Brecon.

Looking back on it, that was quite an ambitious test for a non-walker. Timi is a big trekker now, but not so much back then. I had probably killed her enthusiasm for walking for 10 years until we got into a rhythm of shorter walks.

The route described here is a longer version of the circuit than I used to do for the Girlfriend Test. This was one that I did with a mate a few years later. For the shorter versions of this route, descend on the north-easterly paths from either the summit of Cribyn or Fan y Big and connect back to the east-west road to the Cwn Gwdi car park.
