This lovely 50-ft waterfall can be seen from the Hana Highway right before you get to the very popular Wailua Falls. Near mile marker 45 you'll come to a bridge that crosses Paihi Stream.
The falls are easily visible from the road but getting photo can be tricky...even dangerous. There should be a pullout just before the bridge where you can park and walk to the bridge. Since it is narrow you have to be mindful of traffic. Some folks have also parked at Wailua Falls and walked back to this falls; but again, use extreme caution on this narrow stretch of road.
