Cadair Idris is the Celtic name for the Chair of Idris, a legendary giant Welsh warrior poet, and the anglicised name is Cader Idris. This is Wales’ second most popular mountain and stands at 892 metres and 2927 feet.
Penygadair (Top of the Chair) or the summit is known for its low cloud but on a clear day the Snowdon Massif and the Rhinog Mountain Rage can be seen as well as the Long Mynd, the hills of Shropshire and even Ireland. Just to the north of the summit is the craggy north face, and there are three other peaks on Cader Idris which are Pen-Y-Gader (893m), Mynyyd Moel (855m), and Mynyyd Pencoed (798m).
Cader Idris lies north of the town of Dolgellau and has a number of paths leading to the summit. The Foxes Path is the most direct route leading up the very steep North Face.
Other routes include the Minffordd Path which is 10km long and takes 4-6 hours. The path starts behind the Minffordd Hotel and goes north through woods until reaching level ground where a west turn leads to the summit of Craig Cwm Armach.
From here walkers go downhill and then follow the edge of Cwm Cai, rising up to Pen-y-Gadair and the top of Cader Idris. The other route up is the Pony Path which begins in the Ty Nant car park climbing upwards to the col at the summit before getting to Pen-Y-Gadir after a final scramble.
During World War Two several allied aircraft were lost in the mountains on exercise around Cader Idris as they practiced for air raids on Germany.
