Wanganui can be tricky to cross. There's normally a good ford above Hot Spring Creek but its been moving around a bit the last few years. We have had regular fronts coming through here of the last 6 weeks which as meant that many of these rivers are uncrossable most of the time.
The walk up the valley takes a bit longer now as the road above the power station and up the hill to the quarry has been washed out so you will need to walk from the power station just off the highway. Allow a couple of hours to get to Hendes. Hendes pretty much as described by Southstag.
Cheers
