From Top Camp, follow path to Tunnocks. After passing a large cairn and climbing a few meters more along the Tunnocks path, you reach a flattish area of limestone, grass, and bunda. Leaving the Tunnocks path, turn left and go downslope along the grain of the rocks, pass through a gap in the bunda and find yourself at the eastern edge of a sheer-sided valley. You will see the cube-shaped boulder at the far end of the valley (red arrow in photo). Contour around the right side (north side) of this valley. You will arrive onto flat limestone where you see the cube-shaped boulder and the cave.

[2005 description: "Spacious entrance shaft lands on snow plug about 10m down. At one side (uphill, which is probably roughly east) is a short section of rift, and a slot down one side of the snow plug, but this proved too narrow (at least with 2005 snow levels)"]
20m rope and slings were sufficient in 2005 when snow levels were much higher.
