AreaThe Carneddau
Welsh for 'head or hill of the black hound', Pen yr Helgi Du (832.6 m) stands in the eastern Carneddau on the south-eastern flanks of Carnedd Llewelyn. The two are joined across Bwlch Eryl Farchog, a knife-edge ridge above the cliffs of Craig yr Ysfa. Cwm Eigiau lies to the east and the Ffynnon Llugwy reservoir to the south, and a scattered cairn sits on the western edge of the summit.
