Mynnyd y Glyn is a 377m hill in the South Wales Valley of Rhondda Cynon Taff. This is a nice, fairly gentle, circular walk taking in the trig point and the true summit.
Despite being quite central in South Wales the hill is surprisingly isolated due to poor road access consisting of narrow, winding and occasionally steep country lanes. Parking is also an issue, I parked at the entrance of a farm track, there is just enough room for one car to park and not cause an obstruction. If you want to park lower down you do have more options but the walk will be longer and the ascent considerably greater.
From my parking spot you’ll see the footpath clearly signposted so just follow the farm track all the way up until you get into open fields. From this point on you can see the hill summit so just head towards it, generally following along the line of a stone wall.
You’ll find a gate that takes you onto a track at the bottom on the hill, I followed this round the right-hand side of the hill to bring me up to the East of the trig point. You can then follow sheep-trimmed grass to the trig point and soak up the expansive views.
The trig point is 375m, so I continued North-West afterwards towards the true 377m summit, which is an unmarked and slghtly bleak patch of grass – at least it is on a cold, grey day in December. One thing of interest is the stone wall has been used to make a series of modern cairns, which look like Daleks.
After admiring the views I turn back towards the trig point, but rather than head back up to it I follow the track that goes down to the right of it. This takes you past some crags and towards the gate that I walked through on the way up. Rather than take that gate I instead follow the track right and head South, before skirting around a lower hill and following farmers tracks back to the lane where I parked. A short and sharp uphill section and I’m back at the car.
It’s a nice loop, on a warm day you’ll find plenty of places to sit and take in the views – which will be the Brecon Beacons North and the sea South on a clear day.
