The Carnedd y Bachgen Cairn sits on top of Arenig Fach (689 metres) in the Arenig Mountains of Snowdonia. It has a diameter of approximately 10 metres and shows signs of looting in several places.

A walker's shelter at the summit to the west of the cairn may also be prehistoric in origin. Also to the west a short rock cut track may be a ceremonial approach to the cairn. A boulder situated prominently on this approach may have cup-marks carved into the stone.

This monument is in a remote and wild location and the lack of any recognised paths makes access difficult. However the effort rewards with a very interesting Bronze Age site and spectacular views across the whole of North Wales.
