You start your adventure in an army jeep that takes you on an hour ride to the tubing start point. The guides are very informative, and you stop at an overlook and get to try some sugar cane. Once you arrive, you are fitted with gloves and a helmet with a flashlight. Water shoes are required, and they can be rented for $2 a pair. The leisurely tube cruise takes you through a waterway consisting of ditches and tunnels that were engineered and hand dug in 1870. At the end of your tubing adventure, you will be guided to a picnic area for a picnic lunch next to a natural swimming hole. The cost was approximately $100 a person, and the total time was 3.5 hours. For more pictures, see their website at http://www.kauaibackcountry.com/.
