No joke, if you drive towards Uluru from a certain angle it looks like Homer Simpson taking a nap!
I sent 5 days camping in the bush with WayOutBack Tours back in 2004, and it was one of the most amazing things I've ever done.
The tour consisted of trips to Uluru, The Olgas, West Macdonnell ranges, Kings Canyon and Palm Valley, and 4 nights camping out.
Highlights included sleeping under the stars, Uluru at dawn, walking through the Olgas, a bonus trip of a helicopter ride over a comet crator, and nothing can beat waking up to the smell of coffee brewing on the camp fire.
