Kauai, often referred to as the “Garden Isle,” is renowned for its lush landscapes, cascading waterfalls, and rich cultural heritage. Among its many hidden treasures lies a unique adventure that combines history, nature, and excitement: mountain tubing through the island’s historic irrigation canals. This one-of-a-kind experience offers visitors a chance to float through hand-dug waterways, originally constructed to support the island’s sugar cane industry, now repurposed for eco-tourism.
The Origins of Kauai’s Irrigation Canals
In the late 19th century, the Lihue Plantation established an extensive irrigation system to support sugar cane cultivation. Laborers hand-dug a series of ditches and tunnels, diverting water from Mount Waiʻaleʻale—one of the wettest spots on Earth—to the plantation fields. This engineering feat was crucial for the plantation’s success, as sugar cane required significant water for growth. After the decline of the sugar industry, these canals lay dormant until they found new life as a foundation for adventure tourism.
The Mountain Tubing Experience

Today, Kauai Backcountry Adventures offers exclusive access to this historic irrigation system, providing a unique mountain tubing experience. The adventure begins with a scenic 4WD journey through 17,000 acres of former plantation lands, leading to the canal system. Participants are equipped with tubes, helmets, and headlamps before embarking on a 2.5-mile float through open canals and five hand-dug tunnels. The journey offers breathtaking views of Kauai’s interior, including lush rainforests and the majestic Mount Waiʻaleʻale.
