The Cairn is just about visible from the two main Twr Pem-Cyrn Cairns – with the help of my trusty binoculars.
I headed across the flat but quite difficult terrain (due to the heather/boulders) and after about 15 minutes arrived at the Cairn.
As others have said it is a decent Cairn and worth the extra leg work to visit.
The views are certainly not as good as the eastern Cairns although the distant reservoir glistening in the sunlight was pretty.
There were several possible Cairns/piles of stones along the way.
Which were natural and which man (ad woman) made I have no idea.
One thing’s for sure – there was no shortage of building material for the ancients.
All in all, Mynydd Llangatwg is a good place to visit – particularly when the weather is as good as it is today.
