About Pen y Brynfforchog

Pen y Brynfforchog is a subsidiary summit of Glasgwm in the Aran range of southern Snowdonia, separated from its parent by the pass of Bwlch y Fign.

The summit is bare, marked only by a few stones. The outlook takes in the Dyfi hills, including a direct view of the Craig Portas ridge with Maesglase and Cribin Fawr.

Finding the summit

Surveyor's note

NW of fence junction.

The recorded summit point is small pile of stones. 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 y Brynfforchog is not counted as an independent hill in its own right. In prominence terms it belongs to Glasgwm (779 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 614 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.
