About Aran Fawddwy
Aran Fawddwy is the highest peak of the Aran range in southern Eryri and the county top of historic Merionethshire. It is the only Welsh summit outside northern Snowdonia to exceed 900 m, and nothing in the United Kingdom south of northern Snowdonia is higher.
Creiglyn Dyfi, a small lake on the eastern slopes, is the source of the River Dyfi. The ridge also carries the sister peak Aran Benllyn at 885 m, with Erw y Ddafad-ddu between the two. Dinas Mawddwy lies to the south, Llanymawddwy to the southeast, Rhydymain to the west and Llanuwchllyn to the north on the shore of Llyn Tegid; Bala and Dolgellau are the nearest larger towns.

The Aran Fawddwy group
8 other listed summits sit in the same prominence group, with Aran Fawddwy as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Aran Benllyn | 885 m | 50 m |
| Erw y Ddafad-ddu | 872 m | 39 m |
| Foel Hafod-fynydd | 689 m | 88 m |
| Gwaun y Llwyni | 686 m | 43 m |
| Gwaun Lydan | 632 m | 18 m |
| Pen yr Allt Uchaf | 630 m | 60 m |
| Waun Camddwr | 622 m | 16 m |
| Pen Foel-y-ffridd | 514 m | 114 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.
