Just to echo Pure Joy’s notes, I tried to visit the site a few years ago and could find no trace of any footpath either. As it was nearing the end of the day and I had a friend and her two kids in tow it didn’t seem fair dragging them over the hillside to see ‘some more old stones’. I think they had enough of stones that day to last them a lifetime.
Then the same thing happened to us as PJ – we got lost on the roads too...
