The hike starts out at the Prince Henry Cliff Walk at the popular Scenic World in the Blue Mountains. The length of the trail isn't very long, but it's a very steep drop down to the bottom and the hike back out is quite strenuous. We took snacks with us and hung out the bottom for a while before making the trek back up. There's a great view of the waterfall from the top of the rim at Echo Point that's definitely worth checking out.
