The Tarrenhendre group
3 other listed summits sit in the same prominence group, with Tarrenhendre as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Tarren Cwm-ffernol | 551 m | 64 m |
| Pen Trum-gwr | 513 m | 53 m |
| Mynydd Rhyd-galed | 502 m | 59 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.
