About Drum
Drum, from the Welsh Y Drum meaning the ridge, is a 771-metre summit in the Carneddau, 2 km north-east of Foel-fras. It also goes by the name Carnedd Penyborth-Goch.
Its eastern slopes are drained by the Afon Tafolog, a tributary of the Afon Roe, which runs through the village of Rowen before reaching the River Conwy.

Which hill this one belongs to
Drum is not counted as an independent hill in its own right. In prominence terms it belongs to Carnedd Llewelyn (1,064 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 723 m.
Grouping is by prominence alone: a summit belongs to the nearest higher Marilyn it connects to without a deeper intervening col. Over a large massif that can gather hills no one would walk in a single day, and which few would describe as parts of the same mountain — it is a measure of independence, not a suggested route.
