I live on Ulaino Rd. not far from the falls. I have been turning people around from visiting the falls and helping the landowner (whose land you must cross to get there) for a year now. There are many reasons we want visitors to stay away and most people on the road are in agreement. It is a private road from Hana Hwy. all the way down. Public access has been granted as far as Kahanu Garden but beyond that it is for residents only. The traffic tears up the dirt road and is noisy but that is a small concern. The concern here is that it is a conservation site and has been destroyed by the 1000 visitors per day that was visiting. The o'opu fish(native only to Hawaii) that once lived in the pond are now gone and may never come back. The sunblock and mosquito repellent killed them. The native Hawaiian plants were trampled. And the sacred site to the Hawaiian people was disrespected. This is why it is Kapu.
