I found this while out on a night hike and have been back to it a couple times. It is a relatively large boulder with holds all over it on two sides. There is potential for something harder on the almost blank side.
This thing is kind of a pain in the ass to get to (easier to find when there are no leaves on the trees).
Go to the Buzz Lightyear Boulder. Right next to it, there is a big rusty powerlines pole. If you look at the top, you should see that it's pole number 130. The Jungle Book Boulder is near pole number 135. To get there, walk past the "mushroom drop" and follow the trail as it turns into the woods (this is a wide trail that jeeps used to drive on) and keep going down. You will parallel the highway for a hundred yards or so, and then the trail turns back towards the powerlines. Follow the trail out to the powerlines (passing the old, smashed up car). Follow the obvious powerlines trail until you see it or you get to pole 135. It's on your right. Plow through some annoying underbrush to get to it.
