No special access issues
The approach is around 1 kilometer, but the time will vary a lot depending how you scramble up the gulley. So it might be 30 mins, it might be an hour.
From the parking near the bend in the road, walk up the left side of the steep gulley crossing over to the right side near the top. Once out on the plateau, walk down to the right following the cairns to the boulder.
The gulley is a bit annoying to ascend, there's no real path up the gulley either. So just scramble up, and while on top, follow the cairns. If you have troubles finding the cairns, they are usually further up the hill on the right slanting brown slab.
