Finding the summit

Surveyor's note

trig point (SN 94675 61224) is lower.

The recorded summit point is ancient cairn 270m W of trig point. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

Which hill this one belongs to

Y Gamriw is not counted as an independent hill in its own right. In prominence terms it belongs to Drygarn Fawr (645 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 555 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.
