Grey Crag is the focus of an extensive ridge system stretching out eastwards to the distant Lune and Eden Valleys. Grey Crag lies on the main watershed of the Cumbrian hills, its runoff reaching the sea at both the Solway Firth and Morecambe Bay. The long east ridges have a moorland character and provide easy walking in quiet conditions. The principal tops are Ancrow Brow (1,820 ft), White Howe (1,738 ft), Lords Seat (1,719 ft) and Great Yarlside (1,950 ft). These ridges encompass the valleys of Bannisdale, Crookdale, Wet Sleddale, Borrowdale and Wasdale, the latter two of which should not be confused with their more famous Lakeland counterparts.
