About Moel Lefn

Moel Lefn closes the northern end of the Hebog ridge in Eryri, a subsidiary of Moel Hebog and sister summit to Moel yr Ogof. Beddgelert Forest presses against its eastern side while Cwm Pennant opens to the west, and the Nantlle ridge is well seen from the top.

The mountain is built largely of rhyolite, and the north-eastern flank shows clear columnar jointing in that rock. Two tall upright cairns stand on the eastern side of the hill.

Finding the summit

Surveyor's note

cairn no longer present (23/10/10); rocky outcrop on S top (SH 55307 48503) is lower.

The recorded summit point is rocky outcrop. 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

Moel Lefn is not counted as an independent hill in its own right. In prominence terms it belongs to Moel Hebog (784 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 575 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.
