Two walls (plus the triangular Apex well down the hillside) providing varied climbing, mostly in the Extreme grades.The difficulty, the fact they are not often repeated and shady nature of the climbs makes it likley they will need a brush before being climbed. However, their quality makes this a worthwhile chore!
A good though narrow path leaves the valley and climbs close to the ghyll to the left of the crag, eventually reaching the big Cam Crag Boulders (warm up potential). Go left from here to flank a steep buttress and traverse across to the Lower Crag. The Upper Crag is just up to the right.
