The northern boundaries are clear, beginning on the west with Wastwater and rising up beyond the head of Wasdale to Sty Head Pass, the popular walkers' route to Borrowdale. Across the border on this side are Great Gable and the Western Fells. The boundary continues north to Stonethwaite in Borrowdale, before turning sharply south east along the Langstrath branch of that valley, including the long ridge of Glaramara within the Southern Fells. At the head of Langstrath the perimeter crosses Stake Pass, another pedestrian route, and sweeps eastward down Great Langdale to Windermere. Stake Pass provides the high level link to the Langdale Pikes in the Central Fells. Although falling within the Southern Fells area, Wainwright makes no mention of the low hills between Coniston and Windermere in the Pictorial Guides. These appear, somewhat illogically, within his Outlying Fells volume.
