Follow the Styx – Arahura pack track a further 500m downriver from Grassy Flats Hut to where a signposted track heads left to ‘Browning Biv 2 hrs’. The track is good, and cut across the flats as far as a stream, which it then follows steeply uphill for about 1km before cutting right onto a ridge. The track is well marked, and Browning Range Biv obvious on the ridge above. With a climb of 1000m in a little over 1km, this is a steep, hard ascent.

Note: Described in the reverse direction to your journey

From Browning Range Biv a cut, marked track drops very steeply down a spur, before hitting a streambed and following that down. Once on the flatter alluvial fan on the valleyfloor, a good cut track resumes and heads to the main Styx pack track which it hits 500m downriver of Grassy Flat Hut.
