The Scafells, or Scafell Massif, are a range of fells in the Cumbrian Mountains of England, made up of the remains of a caldera volcano. Fells in the range include Broad Crag, Ill Crag, Scafell, and Scafell Pike, England's tallest mountain. Great End, Lingmell and Slight Side are also usually included within the definition. These hills form part of the Southern Fells.
