Follow the rough road down from SH6. Low ground clearance vehicles
may struggle on the first 50m. There's parking near the cache.
Alternatively park on the side of the Highway - it's only a 2-300m
walk. After rain, there may also be some large puddles/fords on the
road.
The cache container is a camouflaged 400ml sistema box, with a
few small swaps.
You can follow the track to the right of the cache location down
to the river. At low river flows, Ariki Falls is the only waterfall
on the entire Buller river. At high flows it can be a spectacular
rapid.
Take extreme care near the edge of the water,
and keep a close watch on children. Falling in would very likely be
fatal.
Below the far bank of the river is a tunnel that was dug by
miners to divert the river directly across a large oxbow in the
river. This was intended to allow them to extract gold from the
waterfall and the rapids below it. The scheme never worked. In a
kayak, you can paddle into an eddy that water goes into, but not
out of, and you can hear water rushing beneath you! Very
scarey.
This area also apparently has NZ's only deposits of Uranium.
