The hike to get to the falls took us about 2.5 hours, and it wasn't the flattest hike as we had to go up-and-down a couple of times before we eventually descended right down to the bouldery stream on which Curtis Falls resided. The boulder scramble wasn't trivial since the boulders made for awkward footing, and there were a couple of stream crossings where we really had to figure out how to keep our feet enough above water to not make for a soggy hike back out. It was too bad that Mt Taranaki was clouded over during this part of the hike because we could totally tell that the difficulty of the scramble would've been less inconvenient if we always had the summit of Mt Taranaki commanding our attention.

Admittedly, this might have been quite a bit of trouble for such a small waterfall. However, I reckon if you go in with the mindset that you're here for the nature hike and not necessarily just for the waterfall, then you might find this more worth your while than you might expect.
