Without going into details, two less experienced hillwalker friends lost us in the mist, high winds and pouring rain at the summit and we ended up having to descend Knocknadobar North Top ourselves, drive to the pier at Coonanna Harbour and direct them off the mountain as the darkness descended. Luckily they had head torches. It was quite scary for a good hour as we waited first to spot their torches and then watch their tortuously slow descent. We were very close to calling mountain rescue several times. Anyway, they finally made it safely down in the pitch dark and bucketing rain. And after all that, a local householder and landowner (he claimed) stopped them near the harbor as they crossed the ground beside his house. Instead of inquiring as to their safety, he became quite threatening and abusive and at first refused to let them pass his house. But so weary and emotionally worn out were they that they had to simply ignore him and cross his land. But beware, at least one resident of Coonanna Harbour will give you major grief if you even look in his direction. I would tend to avoid this route of descent altogether, in fact.
