There are several companies that offer whitewater rafting adventures in the Great Smoky Mountains with prices that range from $36.99 (with a coupon) to $89.99. Most offer unlimited tubing, although some companies will not allow unlimited if you use a coupon. Some of the higher priced adventures also include lunch and a choice of adventures. Once you complete your whitewater adventure, you can spend the rest of the day floating on your tube down the Little Pigeon River.
