The Western Fells occupy a triangular sector of the Lake District, bordered by the River Cocker to the north east and Wasdale to the south east. Westwards the hills diminish toward the coastal plain of Cumberland. At the central hub of the high country are Great Gable and its satellites, while two principal ridges fan out on either flank of Ennerdale, the western fells in effect being a great horseshoe around this long wild valley. Although lower than its neighbours, Haystacks provides the connection between the Great Gable group and the northern branch of the horseshoe. Immediately to the south east are Brandreth, Green Gable and Great Gable, forming the head of Ennerdale. North west are the well known trio of Buttermere fells, High Crag, High Stile and Red Pike.
