We're off to the Lake District for a week, please throw your top recommendations at me, I really don't know it well and DH only has an eye for climbing mountains.
We'll be near Windermere (with little reception). We like walking, tree climbing, paddling, castles, the sea and are thinking of boating / canoeing.
Kids are 9 and 13. All fairly adventurous though I've got a painful shoulder, and am not as fit as I'd like to be. Also not always keen on crowds, which could be tricky this weekend (didn't think that one through).
