Now I decided to see if I could find an alternative route back down to the base of the valley when I was nearing Lingmell. I have always gone via Lingmell in the past, but my O/S map indicated there was a path, so why not, lets see what it's like.
I left the main path (made a small mistake at first) but soon arrived at this stile - a good sign that a path really did exist. So full of renewed confidence I started a few hundred metres of descent via this route. Hope this is going to be okay, as it's been quite a long day and I don't want to be retracing my steps back uphill again.
