A classic route, adding the two Knockbrinneas. The ridge between Carrauntoohill and Beenkeragh is definitely not for the faint-hearted, and finding my way to the top of Na Cnamha was a bit tricky, as I lost the path at some point, getting me into more scrambling than would have been necessary !! Also note that the descent S/SE of Cnoc Iochtair is rather gentle and is made on firm, grassy ground. I was lucky enough to do this walk on a glorious day, which made it all the more unforgettable !!
