Yeah, it used to be the Swiss Family Treehouse. But then the Tarzan movie came along, and in 1999 Disney re-themed it to coincide with the movie release. The big artificial tree got a giant makeover from the Imagineers. They replaced over 6,000 vinyl leaves and added a new suspension bridge. 6,000!!
It try to take a walk through every other visit or so. The details (as ever, forget about "God is in the details, it's "Disney is in the details) are just lovely. I find something new to check out in the base camp area every time.
