About Moel-yr-hydd
Moel-yr-hydd is a subsidiary summit of Moelwyn Mawr in the Moelwynion of Snowdonia, looking down on the village of Tanygrisiau and its halt on the Ffestiniog Railway, from where the mountain is commonly ascended.
Wrysgan Quarry was worked on the north-east flank from the 1830s until 1946, and substantial underground chambers were cut beneath the summit.

Which hill this one belongs to
Moel-yr-hydd is not counted as an independent hill in its own right. In prominence terms it belongs to Moelwyn Mawr (770 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 566 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.
