About Cadair Idris

Cadair Idris is a long mountain ridge rising from the Mawddach estuary in southern Snowdonia. Its summit, Penygadair, reaches 893m (2930ft) and has 606m of prominence, which makes it a Hewitt, a Nuttall and a Marilyn. Cyfrwy (811m) is 0.8km to the west, Craig Cwm Amarch (792m) 0.9km south, and Mynydd Moel (863m) 1.8km north-east. Aran Fawddwy, the nearest higher hill, is 17.8km to the north-east.

The Minffordd Path, from the south, is the classic route: it climbs through woodland into Cwm Cau, then around the rim above Llyn Cau to the summit. The Pony Path from Ty Nant on the north side is longer and gentler. The Fox's Path, which climbs scree from Llyn y Gadair, is eroded and loose, and many walkers avoid it.

The summit has a trig pillar and a stone shelter. The cliffs above Llyn Cau and the north face are steep, so take care near the edges.
