The crag is the terminal cliff on a short ridge running north west from Bleaberry Fell, dropping about 400 feet (120 metres) 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.

The southern boundary of the fell is formed by Cat Gill, which flows west from Loss Moss to the lake.

Brockle Beck flows north from Low Moss, before turning west to enter Derwentwater at Strandshag Bay.

[2][3] Walla Crag makes a half day or evening walk from Keswick and can be climbed via Brockle Beck, Great Wood (a traverse under the face) or Cat Gill.
