About Gwaun y Llwyni

The top is grassy with a small cairn. Pen yr Allt Uchaf rises across Cwm Cywarch, with Aran Fawddwy north-east, Waun Camddwr north and Glasgwm west.

Which hill this one belongs to

Gwaun y Llwyni is not counted as an independent hill in its own right. In prominence terms it belongs to Aran Fawddwy (906 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 643 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.
