From the trailhead a newly (2017) aligned track crosses Go Ahead Creek and climbs on an old benched pack track to a small saddle and crosses into the Anatoki Valley. The track sidles high above the river, with occasional views, until descending steeply on a zig-zag to Anatoki Bend, passing a few tent sites just before a major side stream.
This is about half way to Anatoki Forks Hut - and the first of many side streams that would be impassable after heavy rain.

From here, it is a gradual persistent climb to the Forks Hut, crossing many side streams (and wash-aways at the time of writing).

Note: Described in the reverse direction to your journey

From the Anatoki Forks hut, the track heads down the valley on the TR, crossing many unbridged side gullies (some which will be unpassable after heavy rain) before reaching Anatoki Bend, about half way to the trailhead. There are some tent sites just up from the side stream, downstream of the Bend.

From the Bend, a steep zig-zag climbs to then sidle high above the river, passing through mixed beech/podocarp forest and regenerating forest.

The track crosses through a small saddle into the head of the Go Ahead valley and descends on an old benched miners track to reach the trailhead (on a well defined but realigned track).
