Maui’s Iao Stream, located in Iao Valley State Park, is a delightful, refreshing rain forest like location at the base of the West Maui Mountains. The stream flows year round from the oft falling rains of the West Maui Mountains. Puu Kukui is the tallest peak in the West Maui Mountains, at 5,787 feet, and receives over 380″ of rain/year making it one of the wettest places on earth.
Iao Valley, and the stream that runs through it, is considered a sacred area with historical significance. Here, at the Battle of Kepaniwai, in 1790, King Kamehameha I clashed with Maui’s army ultimately defeating Maui’s forces which led to uniting the islands and changed the course of Hawaiian development.
Residents and visitors alike find Iao Valley a very special place. Maui’s fresh water Iao Stream is extremely important to life on the island; for, as it is said, ‘by water, all things find life.’
