Have you eber tried the Carrned range, its vitually deserted in comparison, the a5 at Idwal is a carpark. Maybe because you cant really see the peaks from the road, or maybe because of the long walk from the road its not well peopled. The short route up from idwal is very precarious.
Yes, I agree, very peaceful (sshh… don't tell anyone ). I once overnighted at Llyn Cwn on Glyder Fawr in white out conditions, then descended the Devil's Kitchen and up the other side to Carnedd Dafydd and Carnedd Llewelyn - I don't think my knees are up for it now though .
