About Rainbow Kayak - Secret Falls Tour
Paddle the Wailua River with Rainbow Kayak, hike through tropical rainforest and visit Secret Falls on a guided Kauai kayak tour with a picnic-style stop.
Launch your kayak at the mouth of Hawaii's only navigable river and trace the gentle bends of the Wailua into a valley once reserved for royalty. As you glide past jungle banks, your guide shares legends that shaped this lush corner of Kauai.
At the river's north fork the paddles rest and the hiking shoes take over. A shaded trail leads through rainforest dripping with vines and crosses clear streams perfect for a quick cool-down. Just ahead, Secret Falls plunges 120 feet into a natural pool—an ideal spot to swim and refuel with a picnic lunch.
