I wouldn't say it was the only reason for taking this route, but reaching this hidden away sheepfold in Longgrain Gill was certainly a nice bonus.
On more than one occasion I've heard people say that they've worked their way through various lists of fells, with one of the reasons be that "it takes you to places you wouldn't otherwise get to". Well, if you really want to get to some obscure places, try visiting some of these sheepfolds or rather try incorporating them into your routes. Getting to the fell tops is fine; it's something I do all the time so I'm not knocking it. But the summit is nothing more than the highest point, and there's generally much more of interest on the way up or the way back down if you invest the time and effort to explore.
