What it is
This is a guided tubing tour operated by Kauai Backcountry Adventures that floats guests down a historic irrigation system of open canals and hand-dug tunnels. The watercourse was originally built in the 1870s to irrigate the Līhuʻe Plantation's sugarcane fields. The tour takes place on 17,000 acres of private land, part of the historic Grove Farm estate now owned by AOL co-founder Steve Case, offering access to scenery not otherwise visible to the public.
Visitor experience
The experience lasts approximately three hours. It begins with a check-in at the Kauai Backcountry Adventures headquarters in Līhuʻe. Guests are then transported via a 4WD vehicle on a 30-minute ride through the backcountry to the launch point. After getting equipped with a tube, helmet, and headlamp, visitors float for about an hour down the gently flowing waterway. The route passes through lush landscapes and includes passage through five historic tunnels, some of which are completely dark, requiring the use of headlamps. Guides share information about the history of the plantation and the island during the tour. The float portion concludes at a natural swimming hole where a picnic lunch is served. The lunch typically consists of build-your-own sandwiches, chips, and a cookie.

Editorial take
This is a unique, one-of-a-kind activity on Kauai, ideal for multi-generational families, non-swimmers, and visitors seeking a relaxed adventure with a historical component. The exclusive access to private backcountry land is a major draw. It offers a very different experience from ocean-based activities.
However, it is not a thrill ride; the current is very gentle. Travelers on a tight budget may find the cost high for the amount of time spent in the water (about one hour). Those with a fear of dark, enclosed spaces should seriously consider whether the tunnel portions are suitable for them. It is a poor fit for anyone seeking an adrenaline-pumping or physically challenging excursion.
