Altitude: 618m to 858m. Gain: 315m. Loss: 94m . Gradient: 7 deg (Moderate-hard)
Skills: - Extreme rivers (5/5)
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.
