About Drygarn Fawr
Drygarn Fawr is one of the highest points in Mid Wales, rising from the remote moorland plateau of the Cambrian Mountains in Powys, south of the Elan Valley Reservoirs and west of the Radnor Forest peaks.
Its form is gentle, grassy and roughly conical, with a scattering of rock near the top, and the summit carries two large and distinctive cairns. Gorllwyn, Y Gamriw and Drum yr Eira, all above 600 m, lie nearby.

The Drygarn Fawr group
One other listed summit sits in the same prominence group, with Drygarn Fawr as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Gorllwyn | 613 m | 90 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.
