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.
Parked the car at grid SH 753135. Headed SW down the hill to the main car park. From here I picked up the track to take me up to Llyn Cau. From here I headed round to summit Cadair Idris. I then pushed on to Mynydd Moel and Gau Graig. I made my way down through the steep ground to Mynydd Gwerngraig and back through the disused quarry to where the car was parked.
