For a refreshing break from the summer heat, Indiana's lakes are second-to-none—but when you really want to turn it up a notch, check out the variety of water parks around the state. With spraygrounds, wave pools and every type of slide imaginable, the state's water parks will cool the kids down while they have a blast—and parents may not be able to resist a slide or two themselves.
