Heading upriver from Koranga Forks hut, the track crosses the river on a moss-clad swingbridge, before sidling the northern valleyside. The track is well maintained and benched into the hillside. It climbs and falls slightly for a couple of km, before climbing 100m for no apparent reason and emerging onto farmland.

The track is sparsely poled beyond across the grassy faces, dropping quickly back to the river and following it for 1km to the next band of bush. Once here the marked, benchged track resumes sidling above the river for another kilometer and a half to the signposted junction with the Tawa Hut track.

Note: Described in the reverse direction to your journey

Downriver from the Tawa turnoff, the track continues to sidle, benched in the bus for another kilometer and a bit before emerging onto farmland.

The next section is sparsely poled, and sidles low above the river for 1km before climbing steeply just before the beginning of the main bush to enter it 100m above the river.

Once in the bush, the benched well marked track drops back to sidle low above the river (what was that climb all about?). It's a further 2km to the hut, crossing the river just before it on a moss-clay swingbridge.
