Walked this route from Carrick Castle with the local ramblers group. We visited three summits, Cruach an Draghair, Creachan Mor and Cruach a' Chaise. It's quite a steep, rough walk, pathless after leaving the forestry track. We had dry weather, sunny and warm in the afternoon. In mid May the undergrowth wasn't too long, and there were no clegs or midges. I wouldn't want to do it on a damp day in July or August.
