Pen yr Helgi Du

Pen yr Helgi Du rises to 833 meters in elevation within the southern Carneddau range, featuring steep cliffs and a narrow ridge connecting to Carnedd Llewelyn.

The mountain holds deep connections to Welsh geography as part of the ancient region of Caernarfonshire, marked by traditional stone formations at its western edge.

The Welsh name translates to Peak of the Black Hound, forming part of a local naming tradition alongside neighboring Pen Llithrig y Wrach meaning Slippery Peak of the Witch.

Hikers access the summit through multiple routes from Ogwen Valley, with the south ridge path providing direct ascent options for intermediate level mountaineers.

The mountain contains Craig yr Ysfa, a collection of vertical cliffs on its western face, presenting technical climbing opportunities within Snowdonia National Park.
