About Pen Pumlumon Llygad-bychan

Pen Pumlumon Llygad-bychan is a subsidiary top of Pen Pumlumon Fawr and the third highest summit on the Plynlimon massif, part of the Cambrian Mountains in Ceredigion. Ordnance Survey walking maps do not name it, and the boggy summit is marked only by a few stones.

The River Wye rises just south of the top, and the glacial lake of Llyn Llygad Rheidiol lies below to the north. The view takes in Rhos Fawr, Drygarn Fawr and Pen y Garn southward, with Aran Fawddwy, Glasgwm, Tarrenhendre and Tarren y Gesail to the north.

Finding the summit

The recorded summit point is cairn. 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

Pen Pumlumon Llygad-bychan is not counted as an independent hill in its own right. In prominence terms it belongs to Pumlumon Fawr (752 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 691 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.
