Classifications and ratings are the local authority's own and can be coarse — this is a lead, not a guarantee of opening hours or that food is served to non-residents. Follow a name through to the official rating page to check, and confirm before you rely on it.

The Arenig Fawr group
4 other listed summits sit in the same prominence group, with Arenig Fawr as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Arenig Fawr South Top | 837 m | 25 m |
| Arenig Fawr South Ridge Top | 714 m | 21 m |
| Moel Ymenyn | 550 m | 47 m |
| Foel Boeth | 541 m | 42 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.
