About Llechwedd Du
Llechwedd Du is a subsidiary summit of Esgeiriau Gwynion, forming a long peat bog plateau that runs from the end of that hill's south ridge to the higher Moel y Cerrig Duon. The summit stands on one of the large peat hags at the plateau's western edge, marked by a few stones.
Moel y Cerrig Duon, Foel y Geifr and the Berwyn range lie to the east, Gwaun Lydan to the south, and Aran Fawddwy with Foel Hafod-fynydd to the west. A road crosses the plateau at Bwlch y Groes, the pass dividing Llechwedd Du from Moel y Cerrig Duon.

The recorded summit point is ground 5m NW of small quartzite 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
Llechwedd Du is not counted as an independent hill in its own right. In prominence terms it belongs to Esgeiriau Gwynion (670 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 579 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.
