Heading SW along Ngamoko Range from the Iron Gates turnoff, the ridgeline narrows, becoming better defined but also more undulating. Several ups and downs follow including two steep 100m climbs to reach the conical Tunupo highpoint. This is the top of a poled route/track leading west to Alice Nash Heritage Merorial Lodge.

Note: Described in the reverse direction to your journey

From Tunupo Highpoint the Ngamoko Range drops NE in two steep steps, descending 200m before climbing gently over the next 1.5km to reach pt1505. Here a signpost marks the track dropping SE to Top Gorge Hut.
