Altitude: 680m to 859m. Gain: 5m. Loss: 179m . Gradient: 9 deg (Moderate)
Skills: - Occasional rivers (3/6)
The Vane is generally crossable at the confluence unless there's been rain or in high meltwater conditions (early morning is better). The Evans was not crossable at the forks when I visited - the first good (solo) crossing was 800m up river just above the large waterfall which descends the southern valleyside.
A good route follows the northern bank of the Wanganui downstream to the Smyth confluence - mainly on river rock with a few boulder scrambles.
Note that the swingbridge at Smyth Hut has been destroyed (2011). Some parties report crossing 300m above the hut but the nearest viable crossing when I visited (Feb 2016) was at the Vane Evans forks
