back once again with the hill behaviour

We went for a walk up the Blorenge a couple of weeks ago; broadly similar in route and distance to the two previous walks we'd done - the slightly ill-fated (in terms of the health of my ankle and boots) lockdown one in 2021 and the one with some work colleagues all the way back in 2009. So we're not breaking any new ground here but as always there are some points of interest that are worth mentioning, and it serves as an intro to some other more significant walk stuff that we did earlier in the summer and which I'll get to in another post.

So, anyway, I don't want to rehash the content of earlier posts here but you'll recall that the Blorenge is a smallish mountain (or a largish hill, whatever you like, I'm not getting into an argument about categorisation) just outside Abergavenny, really just the steep end of the largest lobe of a sort of cloverleaf-shaped area of high ground centred just north of Blaenavon. Any walk that wants to qualify as an "ascent" in any meaningful way pretty much has to start somewhere in the vicinity of Llanfoist, and it just so happens that there's a car park at Llanfoist Crossing, at the start point of the cycle path that follows the old railway line from Llanfoist to Merthyr Tydfil along some of the bits that haven't been subsumed by the Heads Of The Valleys Road. The only drawback is that the car park is quite small and heavily used by dog walkers so it can be a bit of a bunfight finding a space. I'm not going to be That Guy and suggest you provide minor botheration to the locals by parking on a residential street as an alternative, but clearly that is a thing you could do if so inclined. 

Anyway, you're an adult, sort your own parking out. Having done that you walk up the path that goes under the old Monmouthshire and Brecon Canal and then smashes straight up the hill through the woods directly towards the summit of the Blorenge. On emerging into the open you can, if you so wish, carry on straight up, but a more scenic and less lung-busting option is to take a left turn and head for the pleasant spot of the Devil's Punchbowl, a small pond in what is presumably some sort of glacial cwm. It's apparently man-made, and surprisingly recent (circa 1960s) - it was previously just a low-lying marshy area. Apparently quite a popular wild swimming spot, although when we were there the water level was quite low and it all looked a bit green and murky.

After the brief respite of the fairly flat (even slightly downhill) walk to the Devil's Punchbowl and maybe a brief respite to take in the scenery and have a drink and a KitKat (other chocolate bars are available) you turn south-west and start uphill again, briefly meeting a minor road before turning north for the proper assault on the hill. You'll notice that the path takes a slightly indirect hook-y route before approaching the summit trig point from the north-east and you might be tempted to say: hell, I'm going to cut that corner off. To that I would say: go for it if you want, but I have done it (partly by accident) and generally found it to be a bit of an arse. I mean, you won't die, but the energy and irritation expended in pathless floundering about probably means taking the main path is a better option. You do you, though.

The summit trig point is by a big pile of rocks (which obscure it until the last second coming from the north-east) and, having bagged it and dropped off the top (we went south as this happened to be the direction that got us out of the wind) for a pork pie and a Granny Smith, the walk then drops off the summit ridge to the north-west and eventually joins up with the route of Hill's Tramroad, which includes an exciting tunnel which the kids had some fun exploring and where they shot a video for Huwie's YouTube channel. That path follows the contours round the hillside until it links back with the path up through the woods which takes you back down to where you started.

I think this is the best of the three slightly different routes: the 2009 walk included an extension to loop round the Foxhunter car park and Keeper's Pond (another popular wild swimming spot), which is all very nice but doesn't really add much apart from some lateral distance, and I think the ascent via the Devil's Punchbowl is better than the route along the canal towpath and then an uphill slog along some roads. The 2021 walk took a similar route up (with a bit of inadvertent pathless floundering as described above) but then a much more direct route down, which is fine if you're in a hurry but less interesting than the route incorporating the tramroad and tunnel.

Overall route distance was just over ten kilometres, or about six-and-a-half miles. Details below: latest in the long and varied series of altitude-graph-generating tools is Strava which my Garmin running watch is linked to: this seems not to have the random starting height discrepancy that the old phone app had, which is nice.
