Cadair Idris or Cader Idris is a mountain in Gwynedd, Wales, which lies at the southern end of the Snowdonia National Park near the town of Dolgellau. The peak, which is one of the most popular in Wales for walkers and hikers,[1] is composed largely of Ordovician igneous rocks, with classic glacial erosion features such as cwms, moraines, striated rocks, and roches moutonnées.
From the car park I headed south to get onto the Pony Path and followed this up to the summit of Cadair Idris. I then headed down via the spur down to Llyn y Gadair and past Llyn Gafr to the start point
