In reply to Robert Durran:
I haven't been there recently but based on previous experience,, current Inverness conditions and snow cover around Dundonnel last Sunday I would think it worth a go. I would expect Cul Mor to be ok less sure about the rest. (I would be surprised if Barrel buttress was in condition)
This may be the rose tinted and jealous view of someone who can't go climbing this weekend (or anytime soon)
