if you are a really solid experienced multi pitch trad climber BK would be a good adventure, getting to the base is a bit prickly, we climbed the BK track beyond the large obvious gully then followed a spur on the true L of the gully to where its obvious you need to traverse left to reach the climbs. traverse a long ways left and youll get under the main cliff
the cliffs a big maze of corners, ramps etc. and even though my partner had climbed it 4 times before we still seemed to be lost most of the time
the large obvious roof at around mid height is the great roof (avoid this unless your very good, its had just one free ascent)
to the right of this is hellfire gully which looks more like a vegetated corner, (grade 14-16) and climbing straight toward the roof from a small black slab with corner crack on the left is coercion (grade 17-18) coercion travrses an obvious grey slab leftward beneath the roof, to bypass the roof well to the left, expect a few solid runouts
both these are reasonable routes, however there are large amounts of loose rocks, some sharp edges and engagng runouts
helmet, good trad rack including small cams and long runners mandatory plus double ropes
take some water and snacks its a long day
descend via summit trak to carpark
thats way to little info, ross weiters blog which you can link to from this site has some good pics and im sure there must be others out there with more info
its not for the faint hearted but its a really good adventure
have fun
