So this hike I ended up doing myself. I was under pressure to complete it quickly because a car full of family was waiting for me to complete it. As guilty as I felt about that, i found this hike to be amazing! Canyons, waterfalls, and bamboo forest.
One of the most memorable moments was waking into the bamboo forest and just stopping and listing to the sound of the bamboo knocking in the wind. This grainy poor audio recording from my iPhone does not do it justice.
Then Waimoku falls were wonderful too.
