Carnedd Dafydd Mountain

Carnedd Dafydd is a mountain peak in the Carneddau range in Snowdonia; at 3,425 ft/1,044 m, it is the third highest peak in Wales. Situated south-west of Carnedd Llewelyn and north of Pen yr Ole Wen, Carnedd Dafydd is on the main ridge of the Carneddau, and on the border between Gwynedd and Conwy.

Like most of the summits in the southern Carneddau, it has a flat, boulder-strewn summit plateau. Immediately to the north lie the crags of Ysgolion Duon, well-known to climbers.

The origin of its name, which translates as Dafydd's (or David's) cairn, like that of its neighbouring peak, Carnedd Llewelyn (Llywelyn's cairn), are named after Llywelyn ap Gruffudd, the last independent prince of Wales, and his younger brother, Dafydd ap Gruffudd.
