Moel yr Ogof...the ‘Hill of the Cave’.... is a 2,149ft mountain rising to the north west of Moel Hebog, separating Cwm Meillionen from Cwm Llefrith. Its claim to fame – and, indeed, reason for its name – is a cave high up on its eastern face where Owain Glyndwyr is said to sleep until called upon to do whatever slumbering heroes do when rudely awakened.

Moel yr Ogof possesses another, much more tangible treasure upon its brutally exposed summit, however... a Bronze Age funerary cairn. Ha! According to Coflein it is:
‘A roughly circular cairn of approx. 1.2m in diameter which is situated on level ground adjacent to a summit. Comprised of stones varying in size between 0.2m – 0.3m, there are two possible capstones over a hole in the ground that could be a cist. Noted during an upland survey conducted by Archaeophysica during 2005-6‘
