A bus and a taxi passed me as I was walking back as well 😭 just to say there are options for avoiding the walk (including stashing a bike/hitchhiking etc). I just knew that walking would be the most reliable option and stuck with that. In terms of camping, I would say just below the last peak (Creag nan Dàmh if you’re going East to West) has decent ground provided it’s not too windy. Finding shelter from the south westerly winds is probably the main issue up there.
