Foel Fadian is a neat hill/small mountain to the NE of the great Pumlumon massif overlooking the awesome crags of Uwch-y-Coed and the lovely tarn of Glaslyn. It goes without saying that the views are superb, particularly towards the great Bronze Age cemetery that is Pumlumon itself. To be honest that would be more than enough. However the 1:50 Landranger map also shows an ubiquitous 'tumulus' sited upon its eastern shoulder...... always a welcome discovery, it has to be said.
According to Coflein it is 'a round, ridge top, earthen mound, 22m in diameter and 2.0m high, apparently undisturbed barrow'. Hmm... maybe, maybe not - but then again to say there are a few precedents in the area would be an understatement of monumental (sorry!) proportions, so happy to go along with this, I guess.
Needless to say my visit coincided with some absolutely appalling weather, with winds gusting in excess of 50mph, so no barrow photo - although I did manage to grab one of the view. Which was nice. The site is best approached from the Vaughan-Thomas memorial (quite a dude who apparently walked the length of Wales aged 70 - right on!) on the minor road to the north-east. Not a difficult walk considering the terrain.
P.S - off topic, but you might also want to take a look at the excellent waterfall of Ffrwd Fawr a little to the east of Dylife..... but careful now.
