The track starts off along a farm road across the valley floor, before entering the bush alongside Wainui River. As the valley narrows, the track climbs up the hill slope above the true right of the river. There is steep drop to the river below, so it is important to keep children supervised here. Though narrow in a couple of parts, the track is mainly wide enough to allow people to pass in both directions. The bush is lush, with many ferns, vines and nikau. The track arrives at a suspension bridge which crosses to the true left. Below, Wainui River flows down among large granite boulders. The waterfall is located a few hundred metres beyond here.

Wainui Falls are 20 m high cascading falls. The track ends at a small concreted area that provides a great view of the waterfall. You can swim in the plunge pool, though there is a strong current flowing from the base of the waterfall. There are several pools further downstream that are good for swimming; you can access these by boulder-hopping down the river bed from the plunge pool.

Return the way you came.
