Most photos of Hanging Rock are taken from Baltzar Lookout and look like this.

There are a couple of options to get the alternative, and far more spectacular view from the bottom.

One option is to descend into the Grose Valley from your tourist track of choice, and locate the ridge that starts at 513720E 813590N and ascend to the SW, steeply at first, then up broad open terraces to the boulder field.  There’s no lawyer vines around these parts - you’ll occasionally brush against a shrub.

After ascending 400m, the open lower story becomes strewn with larger boulders. As you wander, keep looking upwards through the canopy to catch sight of the Rock. It is visible from various places as the landslides have destroyed trees and left boulders as vantage points.

The boulders at the base are easy to negotiate, this was taken from close to the base of the climb.

The cliff between the Lookout and the Rock is overhung and falling away, so tread lightly next time you’re up there.

An alternative route to get the base is along Hat Hill Ridge, into the canyon, down Lews Pass and then follow the top of the talus slope for 900m to the NW. Note that following the highest ledge (the one at the same level as Lews pass) for 700m will lead to a point of extreme exposure just under Baltzar Lookout. There is a faint footpad along both the ledge & the talus… choose wisely!  The shot below was taken from below the Lookout (evidence of man-made debris confirmed the location), where is can be seen that the 700m ledge fades to nothingness.

The full majesty of Bald Head is easily visible from the ledges on the route to Hanging Rock. Of note is the climbers track that appears from the vegetation at the left edge of the Head and can be followed around to where the vegetative fades to bare rock. There’s a bit of exposure with some parts roped… possibilities for further exploration…

This looks like a fish-eye lens was used, but it’s just the curvature of the cliff edge from almost directly underneath it.  The shadow of the nose travels down the rock as the sun rises, a beautiful  natural sundial.

The round trip from Hat Hill Ridge, to the Rock, and then down the Grose and back up Perrys is shown below.  A short car/bike shuffle will save a dusty 45 mins through the Park. Or alternatively return the way you came in.
