Ennerdale Water has a reputation for being an out of the way place and is arguably the most difficult of all the lakes to reach. Well, not so if you live on this side of the Lake District. For me, the lake and its surrounding fells are actually the closest to home. The upshot of its reputation is place where you ( or me ) can usually walk without meeting the crowds found in some other areas of the Lake District.
Unless there happened to be some sort of special event on, I'd go as far as to say this is some where you're guaranteed to get a parking space, and it's free.
