Upper Makamaka'ole Falls. (The name means "without friends" ... read on.) There are many tiers to the fall, but this was the only reasonably safe level to access. Having said that, on the way out I still managed to slip on some slippery rock, landed on my knee in a most unkind way, and hoping I havent bugggered my trip up. I was able to walk and hike the rest of the day, but now bed bound unable to really move my leg much.
