Everybody in the family will have a blast here, but unfortunately, you have to be 36 inches tall to zoom down this hill, around its curves and off its jumps. Choose from one- or two-person tubes to add to the fun. Knowing that you will want to do this, go ahead and buy your tickets online in advance to save 20 percent. The Tubing Hill is closed on Wednesdays for grooming, so plan accordingly.
