Joffrie Falls in Karijini is at the bottom of a Class 5 hiking trail into the canyon. It's a tough hike to get there, but you're completely alone once you're on the ground. Imagine being on your own at the bottom of a 4 billion year old canyon, with crisp water available at your feet to cool off in at the end of a tough hike. It's like paradise hidden at the bottom of the world.
