About Rhinog Fawr
Rhinog Fawr stands in the Rhinogydd of southern Eryri, the third highest summit of that range behind Y Llethr and Diffwys. Rhinog Fach lies to the south across the pass of Bwlch Drws Ardudwy, and Moel Ysgyfarnogod to the north.
As across most of the Rhinogydd, the ground is hard sedimentary rock smothered in heather, which slows walking considerably. Llyn Du, a small tarn set among crags at around 510 m, sits below the summit. The Roman Steps pass gives the usual line of approach from the north-east or north-west.

Finding the summit
rock by trig point 25m W at SH 65675 29012 is 1m lower; rock 5m S of cairn is 10cm lower.
The recorded summit point is rock 8m W of cairn. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

The Rhinog Fawr group
One other listed summit sits in the same prominence group, with Rhinog Fawr as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Craig Llyn Du | 553 m | 37 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.
