Beginning 1 km south of Kaiaraara Hut, South Fork Track follows an old bridle track to Mt Heale Hut and Mt Heale. It crosses the stream twice then climbs steadily to a swing bridge on the way to the central ridge. It travels through regenerating forest with excellent examples of tutu.
Warning: There is approx. 500 m at the first stream crossing at the Forest Road end of the track where you need to follow the orange marker posts up to the central ridge, climbing out of the stream.
Note that the river rises quickly after heavy rain.
