About Esgeiriau Gwynion

The Welsh name Esgeiriau Gwynion translates as 'white shanks'. It is the smallest of the three Marilyns of the Aran range, the others being Aran Fawddwy and Glasgwm.

Lying east of Aran Fawddwy across the gap of Bwlch Sirddyn, the hill curves round Cwm Cynllwyd towards the Berwyn range at Foel y Geifr. Its tops are boggy throughout, rising from a wild plateau of peat bog that a road crosses at Bwlch y Groes.

Finding the summit

Surveyor's note

ground 30m NE, by small cairn, is 0.3m lower.

The recorded summit point is no feature. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

Twelve highest shown, of 17 in the group.

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.
