If it's summertime and you're starting to stick to your couch because the weather is so hot, consider visiting one of the country's many outdoor water parks to cool you down. You might think (correctly, in some cases) that some parks are so expensive that you might as well rent your own island, but many offer deals to make the experience affordable.

Check out our list of the best water parks in the USA. You could also click here for cheap water parks deals in your area, or check out our list of the best indoor water parks in America.
