About Mynydd Graig Goch
Mynydd Graig Goch 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. For many years it was excluded from lists of the Welsh 2000 ft mountains because of a spot height of 609 metres (1,998 ft) on OS maps. However, this changed in 2008; after years of speculation a group of hillwalkers carried out a precise GPS survey of the peak, measuring the absolute height as 609.75 metres.
