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.
Took a group of Coleg Menai Students up as their 2nd peak on welsh 3 peaks. Started at 6 am. Can`t recall time back down. After this we drove south and went up Pen Y Fan.
