After the success of Ridge's first suggestion I decided to tackle his second suggestion, Hallin Fell. I found this tougher than Latrigg (Latrigg was tougher than Walla Crag) although not by leaps and bounds. I tried to follow the route from
here but on the decent the paths on the ground deviated from the route a bit and I found myself walking along a path nobody else was using. I got to here:
and slipped and fell down the hill a bit as the grassy path was steep, wet and slippery. Not knowing if I was in the right place or not and not wanting to venture further in case the path got steeper I turned around, climbed back to the summit and returned the way I'd come. So not quite the walk I wanted but enjoyable (less so the descent as I had to go so slow) and great views so thanks Ridge and on to my next adventure.
If anyone wants to see the photos they're on my Flickr.
