Park at the corner of Blaxland and Terrace Roads, West Killara. Take the service trail past the "Lane Cove National Park" sign 150m until the Great North Walk marker on the left. [The track ahead goes to "The Big Pump"]. Turn left onto the GNW and proceed 300m, past a rising cliff, a complete overhang, and a waterfall. The boulder is right in the middle of the Great North Walk.

Grade Route

These climbs are right on the Great North Walk as it runs beside the boulder.

Yet another problem that's been vandalised. The starting flake is bit smaller than it used to be. Jump from the starting flake to the next flake and then straight up.

One of the best 5s in Sydney. Start right hand in the pocketey side pull just left of the scoop and go straight up aiming for the nice uncut just left of the scoop up high. Nails.

These climbs are on the rear of the boulder.

There use to be a big edge on the State Of Origin problems but some vandal smashed it off, so you now need to pop for the smaller holds in the break.

From the arete traverse right finishing up Bog On Up.

About half way between the arete and Bog On Up is a faint feature around head height with two slopes on either side. Grab the slopes and make a series of desperate slaps to the right finishing up Bog On Up.

Mantle the good holds

Start on the lowest holds and pop for the small edges then up over left. There used to be a big edge, but it has been smashed off so this is now probably harder than V3.

Sit start and a long reach. The arete and the big edge half way up on its left are off. Mike Croker

Right of arete, starting very low. 'Arete' is off.

Easiest way off the Block

Overhang 10m right of The Block

Start on obvious jug. Needs some repeats to confirm grade. Good start sequence.

Since the jug has been smashed off by some vandal this may be undoable by mere mortals.

Start in the back of the cave, up out over the jugs and wrestle with the tricky finishing mantle.
