A subsidiary ridge breaks off south-west from Sourfoot Fell, crossing the slight hump of Loftbarrow before reaching Darling Fell (1,282 ft). This stands over the northern shore of Loweswater, about halfway up the lake. Between Darling Fell and Low Fell is the little valley of Crabtree Beck. In general, the western slopes of the Low Fell ridge are long and gentle, while some rock appears along the steeper eastern and southern flanks.
