Flumin’ Kohala—Exploring the Kohala Ditch

Big Island • March 27, 2020

The Kohala Ditch has been called a masterpiece by some of those who, over its 110 years of existence, have explored the route from its headwaters in the high forests of the Kohala Mountains to its terminus over 20 miles away in the lowland sugar cane fields near Hawi.

Hand drilled and blasted over a century ago out of solid rock deep in the canyons of Kohala, “The Ditch” brought water and prosperity to the people of Kohala. Hundreds of brave men risked their lives, and many perished, in its construction. To this day, the Ditch remains witness to a heroic feat of engineering skill, physical prowess, and, above all, human determination.

Flumin’ Kohala offers a rare opportunity to explore this remarkable hand-wrought wonder and the pristine Hawaiian landscapes it crosses. Join them on a guided tour through three scenic miles of Hawaiian history. Seated in custom four-man kayaks, guests delve underground and float through 1,000-foot tunnels dripping with spring water.

Flumin’ Kohala has garnered many five-star reviews on TripAdvisor in which customers have lauded the company’s knowledgeable guides who provide lots of information on the island’s history and culture as only locals would know. The amazing views are complementary!

Soar high over rushing streams and float across the mountainside via elevated flumes. Quietly meander through thick forests by way of winding concrete channels. Go flumin’ to see, touch, hear and feel the hidden beauty of Hawai‘i. Leisurely paced, educational, fascinating and fun, it’s the perfect Hawaiian eco-activity for families and groups.
