Mountain rank by height: 175 out of 188
Height: 2,031ft | 619m
Region: Brecon Beacons
Grid ref: SN988216

I’ve not included a Google Maps of Y Gyrn currently as Google Maps has it completely in the wrong place – it shows it as being a few metres away from Pen y Fan. Pen y Fan is over 200m higher and a good walk away from the 619m Y Gyrn.

Access to Y Gyrn is very easy and the walk from the upper Storey Arms car park is about a mile, with only just over 600ft of ascent. This would be a very child-friendly mountain to climb as the distance is short, the height gained not much and the paths are clear and easy.

Fan Fawr is across the road from Storey Arms, so the car park for this walk is below in this shot. | Tokina AT-X 50-250 @ 50mm, f11.

I took the reddish path up that takes you directly towards Corn Du, so the views of that summit and Pen y Fan are constant and clear. When you reach the crest of the ridgeway you will find a rough track heading left to the summit of Y Gyrn. You can take a more direct route up, which takes you on a diagonal trail right from the gate next to Storey Arms – however, to make it more of a loop I took the gravel track up and the diagonal grassy track down.

Following the path along the ridgeway leads you parallel to a fence, the summit of Y Gyrn is marked by a small pile of stones with a piece of wood poking up from it. This is on the other side of the fence to the path I was on.

This is definitely a mountain you can easily tick off if you were heading towards Pen y Fan or Corn Du and provides a different perspective on those two mountains than the main track up to them from the lower Storey Arms car park.

As the loop I did was only two miles, it is probably worth walking on to at least Corn Du afterwards, unless, like me on this occasion, you were just looking for a quick and easy summit.
