Initially an easy track from the Nina trailhead, we tried a 'short cut' and met/found a newly cut and marked route to the Sylvia tops at the 860m contour. I expect the marked track would be continuous from the river and recommend using it rather than this 'short cut'.

The climb is, as expected, steep - the cut track certainly makes it easier.

Note: Described in the reverse direction to your journey

Rather than follow this 'short cut', follow the marked track down to the river, cross to the TL and continue on-track to the Nina Track. Turn right (east) on an easy track to the Nina trailhead.
