I have been out the last two days with Falkirk Outdoor Activities. Yesterday, we traversed from the Aonach Mor Gondola to the CIC Hut via the East Ridge of Carn Dearg Mheadhonach. Although this is a good winter route, I would not recommend it in summer conditions.
Today we continued to Glen Nevis via Ledge Route on Ben Nevis.
We did not encounter snow during the two days. I looked down Number 4 Gully during our descent. There are a number of large rocks waiting to fall as the remaining snow retreats. I would not recommend this route at the moment.
