About 20m to the left of 'Porthole Ridge' is another ridge marking the western boundary of the top pitch of 'Porthole Crag'. Still further to the left is a second sharply defined ridge having on its left boundary a vertical red face forming a recess with the buttress on its right. In this recess grow two large bushes about half way up, immediately below the brown face. The climb follows the line of the ridge keeping to the left of the edge where most of the climbing is on a flat face.

Start approximately 150m west of 'Breakfast Run' where there are no bushes on the slope below the climbs. The climb starts on a white slab facing towards Hartebeespoort Dam. The slab gets progressively steeper until it reaches the steep arete.
35m 11 Climb the centre of the white slab (a little thin near the top) passing right of a tree which has no low down branches and which projects from the face at 65o. Continue up past a cluster of bushes, then traverse right across a gully and under some overhangs into a black recessed stance which can be clearly seen to the right when approaching the foot of the climb.
25m 10 Climb above the belay stance on the right hand edge of the arete (still facing the dam) and up to the easier rock above.
Note:
The climb appears to enjoy more winter sun than most others in the area.
