When you arrive at our launch site you’ll grab a tube, don a headlamp, and jump in the gently flowing waters. Witness Kauai’s spectacular, historical engineering feats as you float down the open canals, through several amazing tunnels and flumes engineered and hand dug circa 1870. Enjoy the wonder and magic of each tunnel, lit by headlamps. At the end of your adventure, you will be guided to an enchanted picnic area nearby, for a delicious lunch and a cool dip in a natural swimming hole.
