The Vale of Keswick, provides separation from the Northern Fells whilst to the west runs the long valley of Borrowdale. The parallel eastern boundary is created by Thirlmere and the St Johns in the Vale. Grasmere to Windermere forms the remainder of the eastern boundary. In the west, Stake Pass descends into Great Langdale.
