Waimano Valley Professional Review and Guide
"There are lots of wild fruits and berries along this trail. The loop is a short sample of the much longer Waimano Trail, which struggles steeply up toward the rainy Ko’olau mountains. Overlooks along the upper section offer vistas over a patchwork of lacy textures and colors created by the treetops in Waimano Valley. Once you have descended to the valley floor, walking alongside a little stream, you can experience the forest more intimately from below the canopy.
You can do this hike in either direction, but it is described counterclockwise, beginning on the upper trail and returning on the lower. There are so many kinds of wild fruits and berries along the route, you won’t make much forward progress in spring and summer if you try to sample them all. Surinam cherry, strawberry guava, Java plum, and mountain apple are all edible in season. Do not try anything you cannot identify with complete confidence."
