Begin through luxuriant beech forest on the Loop Track in Kerr Bay. Where the track turns south to sidle above Lake Rotoiti take the left track eastwards towards the St Arnaud Range Track. 

This trail zig-zags to the bushline and climbs to Parachute Rocks, where a calendar-worthy spectacle is spread out below: the familiar profile of Mt Robert, the diminutive bridge at the outlet of the Buller River.

After four hours, the ridgeline is reached. 

Head south along the undulating ridge, walking over Pt1787. At the saddle beyond this high point, turn left and descend scree and sidle through tussock to reach the giant tarn that feeds Rough Creek – truly a diamond in the rough. 

Suitable tent sites can be found around the tarn. 

Next day, continue north over a saddle in the spur between Pt1787 and Pt1736. The basin below is filled with more tarns, this time feeding Merry Stream. Climb to the ridgetop once more and rejoin the St Arnaud Range Track back to Kerr Bay.
