Start: Purakaunui Falls Car park
(S/E) The path starts on the opposite side of the road from the car park. It's a well-marked path, fairly easy to follow. You descend through the forest all the way, before crossing the stream once and winding your way down to the waterfall.
(1) At the waterfall, enjoy this bucolic spot, then retrace your steps back to the starting point (S/E).
