Cadair Idris from the summit of Tarren y Gesail to the south, across the Dysynni valley. Mynydd Moel is the peak on the right of the central bulk of the mountain. Far right is Gau Graig, the most north-easterly peak of the Cadair Idris massif, crowned with a probable prehistoric enclosure. The summit of Arenig Fawr can be seen over the top of the ridge between the two. The distant peak far right is, I think, Rhobell Fawr.
