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.
Got a drop off at 286M CP which is at the top of the Cadair Valley road. Walked around to the north ridge on Mynydd Moel. Took the group up the grade 1 scramble up to the summit of Mynydd Moel. Then walked over to the summit of Cadair and then walked down via stone shoots to Llyn Cau and down to Cadair gates car park for a pick up. The group where 14/15 years old with 10 in the group. They wore helmets on the scramble but where not roped together.
