Cefn Gwyntog

About Cefn Gwyntog

Cefn Gwyntog is a top of Cyrniau Nod in north-east Wales, within the section of the Berwyn range known as the Hirnantau. Its summit lies just outside the Eryri boundary.

The small cairn on top sits amid peat bog and heather that can reach knee height, and the hill has a reputation as one of the hardest summits in Wales to reach, a consequence of both its remoteness and the walking terrain. Views are extensive but the surrounding moorland is flat and featureless; Llyn Efyrnwy lies below.

Finding the summit

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.

Which hill this one belongs to

Cefn Gwyntog is not counted as an independent hill in its own right. In prominence terms it belongs to Foel Cedig (668 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 587 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.
