In reply to spidermonkey09:
The route finding is easy enough, there's a reasonably comprehensive set of instructions in the back of the slate guide. In terms of technicality, the hardest bit to get up is the chain, but this a) isn't that hard and b) can be aided anyway if you have carabiners which are large enough to clip into the links.
The only tricky bit to find is the passageway from Dali's hole to the bottom of Australia. It's located behind a boulder in the corner of the wall adjacent to the first bit of flat grass you reach once leaving California. The word "tunnel" is even scratched on the rock above it. Furthermore, the lost world no longer has any trees or a pond thanks to a recent rocklfall.
Alot of the dodgy ladders have been "repaired" recently with cord, and the bridge of death has collapsed, so the route is a lot safer/less scary than it used to be.
