Walla Crag is a fell in the English Lake District, near Keswick. The fell is a popular short walk from Keswick and gives superb views over Derwentwater. The western face is prominent in views across the lake and fine views over Keswick are available from the summit.The crag is the terminal cliff on a short ridge running north west from Bleaberry Fell, dropping about 400 ft from the plateau above.
The summit lies a little way back from the brink, the smooth heather-clad hinterland then dropping to the broad depression of Low Moss. Beyond here the ground rises again to Bleaberry Fell. The southern boundary of the fell is formed by Cat Gill, which flows west from Loss Moss to the lake. The gill separates Walla Crag from the neighbouring Falcon Crag, popular with rock climbers. Brockle Beck flows north from Low Moss, before turning west to enter Derwentwater at Strandshag Bay.
