Waitahu River is just a few km out of Reefton off Gannons Road on SH69 heading towards the Buller Gorge. It’s a one road in one road out track that runs alongside the Waitahu River.
This track will be different every time you ride it as it’s state is very dependant on recent weather conditions. The track can range from relatively smooth wide dirt, to gravel, to single track, to mud to riding through the middle of a stream, to riding over sections of large rocks, all in the same ride. How far you can get along the track will also depend on recent weather conditions as the river can alter course, wash away the banks and deposit rocks and other debris across the track.
