Finding the summit
trig point 35m SW (SO 02362 81221) is 1.75m lower.
The recorded summit point is ancient cairn. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

The Pegwn Mawr group
4 other listed summits sit in the same prominence group, with Pegwn Mawr as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Crugyn Llwyd | 571 m | 40 m |
| Camlo Hill | 509 m | 130 m |
| Brondre-fawr Hill | 508 m | 60 m |
| Moel Hywel | 505 m | 133 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.
