Knott Rigg is a fell at the head of the Newlands Valley in the English Lake District. It is situated some 8+1⁄2 kilometres south west of Keswick and has a modest height of 556 metres. Its name is derived from the Old English language and means “hill on a knobbly ridge”. Despite its modest height, the fell is listed on a number of hill lists, including the Birketts and TuMPs, and also has its own chapter in Alfred Wainwright’s Pictorial Guide to the Lakeland Fells.
