About Moel Hebog
Moel Hebog — 'bare hill of the hawk' in Welsh — dominates the view west from Beddgelert, rising to 783 metres. It is the chief summit of a range running through the north-western corner of Eryri that also takes in the Nantlle Ridge and Mynydd Mawr.
Geologically the mountain is made up of a complex sequence of Cambrian and Ordovician rocks, including volcanic formations belonging to the Snowdon Volcanic Group. Its main secondary tops are Moel yr Ogof at 655 m, which holds a cave traditionally linked with Owain Glyndŵr, and Moel Lefn at 638 m. A Marilyn, Hewitt and Nuttall, it draws walkers for wide views taking in Snowdon.

Finding the summit
natural ground by raised trig point at SH 56483 46943 is 1.4m lower.
The recorded summit point is elongated rock 10m NNE of cairn. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

The Moel Hebog group
2 other listed summits sit in the same prominence group, with Moel Hebog as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Moel yr Ogof | 655 m | 118 m |
| Moel Lefn | 638 m | 63 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.
