Kauai, the “Garden Isle” of Hawaii, is a haven for adventure seekers. Among its myriad offerings, three activities stand out: mountain tubing, ziplining, and kayaking. Each provides a unique perspective of the island’s lush landscapes and rich history. This guide delves into these adventures to help you choose the one that best suits your thrill level and interests.
Mountain Tubing: Float Through History

Embark on a journey through time with Kauai’s mountain tubing adventure. Operated by Kauai Backcountry Adventures, this activity takes you through the historic irrigation canals of the former Lihue Plantation, hand-dug in the 1900s. As you float on inner tubes, you’ll traverse lush landscapes and navigate through dark tunnels, all while soaking in the island’s natural beauty.
Highlights:
- Scenic Views: Marvel at vistas of Mt. Waiʻaleʻale, one of the wettest spots on Earth.
- Family-Friendly: Suitable for ages 5 and up, making it perfect for families.
- Historical Insight: Learn about Kauai’s sugar plantation era as you float along the canals.
Considerations:
- Claustrophobia: The tunnels can be narrow and dark, which might not be suitable for those with claustrophobia.
- Advance Booking: This popular activity often sells out weeks in advance.
Ziplining: Soar Above the Canopy

Experience the thrill of soaring above Kauai’s lush landscapes with ziplining. Companies like Koloa Zipline and Outfitters Kauai offer courses that let you glide over forests, valleys, and rivers. Koloa Zipline boasts the island’s longest zipline—the 4,000-foot FlyLine—providing panoramic views of the South Shore’s beauty.
