Oct 2024 - Ascent from Nebo. Mynydd Graig Goch (Welsh, 'mountain of the red rock') is the western end peak of the Nantlle Ridge, and is a subsidiary summit of Craig Cwm Silyn. It is also the most westerly 2000 ft peak in Wales.It was my first time up here! The summit is boulder strewn, crowned by several tors of rock, of which one is the true summit. The southern and western flanks consist of large boulder fields. The north-east face has steep cliffs, that form the backwall of the glacial Cwm Dulyn. Cwm Dulyn's lake Llyn Cwm Dulyn contains a population of Arctic char. Set off at around 1:15pm as the morning was clagged. Really enjoyed the walk. The Welsh flag and the Gynynedd flag adorned the summit. Not a soul seen.
