Wailua River Adventures

4.57
Kauai’s Wailua River flows from Mt. Waialeale past lush jungle landscapes and hidden waterfalls, creating the perfect setting for outdoor adventure. Paddle a kayak through calm, scenic waters to explore secret falls and ancient sites, or take a relaxing boat cruise to the famous Fern Grotto. Whether you're chasing waterfalls or enjoying the ride, the Wailua River offers one of Kauai’s most rewarding nature experiences.
Pro Tips
  • - Bring bug spray. The Wailua River winds through heavily forested areas in one of the wettest places on earth, but a quick spray before departure will make for a much more enjoyable trip.
  • - Some tours will also let you dock your kayak and embark on a hike to secret waterfalls tucked back into the rainforest.
