The Northern Fells are a part of the Cumbrian Mountains in the Lake District of England. Including Skiddaw, they occupy a wide area to the north of Keswick. Smooth, sweeping slopes predominate, with a minimum of tarns or crags. Blencathra in the south-east of the group is the principal exception to this trend.

The North Western Fells are a part of the Cumbrian Mountains in the Lake District of England. Including such favourites as Catbells and Grisedale Pike, they occupy an oval area beneath the Buttermere and Borrowdale valley systems. The North Western Fells are characterised by soaring east-west ridges and an absence of mountain tarns.
