Waipio Valley is the largest valley on the Hamakua Coast on the island of Hawaii. The Kohala Mountains — into which Waipio Valley is carved — receive over 300 inches of rainfall a year with numerous waterfalls that plunge off its cliffs over a thousand feet into Waipio Valley.
Olapa trees and hapuu ferns overlook a waterfall as it cascades down a series of pools before its final plunge deep into Waipio Valley. This waterfall can be seen from a trail at the end of White Road in Waimea that leads through the Kohala Forest Reserve and follows the rim of Waipio Valley.
Ferns thrive on the walls of a plunge pool as a waterfall cascades down the northern wall of Waipio Valley.
Hiilawe Falls, the highest waterfall on the Big Island, drops over a thousand feet to the valley floor below and then meanders as a charming stream through a series of cascades, rapids, and pools. White ginger, ferns and other plants thrive along the banks of the stream as it makes it way to the sea.
