Wikipedia: A water park or waterpark is an amusement park that features water play areas such ass wimming pools, water slides, splash pads, water playgrounds, and lazy rivers, as well as areas for bathing, swimming, and other barefoot environments. Modern water parks may also be equipped with some type of artificial surfing or bodyboarding environment, such as a wave pool or flowrider.
