The track largely follows the construction of the Matiri Hydro scheme.
Once across the West Branch bridge (care is needed after heavy rain in the headwaters, do not cross in these conditions), follow the road alongside the river before entering forest and climbing the face of a slip brought down by an ancient earthquake. The track levels and soon reaches Lake Matiri Hut overlooking the tranquil Lake Matiri.
Continue past Lake Matiri Hut on tracks to the upper Matiri Valley and 1000 Acre Plateau.
About 6 km north of Murchison, just north of the bridge over the Buller River, turn off SH6 onto Matiri Valley Road. Continue for about 16 km to reach the roadend carpark.
