When asked for a Waimea Canyon lookout, Google Maps took us to an essentially arbitrary place on Waimea Canyon Drive with perfectly decent views of the canyon, rubbish parking, and a rather scary dropoff. But coming up Waimea Canyon Drive meant that we ran into another essentially arbitrary place with truly terrifying parking: the Red Dirt Falls, about 2km south of the fork with Kokee Road.
