Excellent walk. I would recommend walking boots. It's an interesting walk that has its challenges but is very manageable. Fantastic sounds and sights, some of which are dramatic and a little scary. About a third of the way in near the waterfall make sure you dip between the rocks and take a good look at the waterfall, it's just of the path. We managed 95% of the walk before it became too difficult. When you getvthe stream 30% of the way through, keep going, cross the stream and climb, the path does come back. Also after the stream go up the path ro the right for another great view.
Walking only, you will need to go over and under some fallen trees.
Fantastic 2 hours.
There is a little car park near by for about 6 cars.
