A splash pad is a location within a waterpark that had water jets, sprayers, or mist. Its function is to allow children to play in and cool off during the summer. A splash pad does not accumulate water like a pool.
A splash pad is not the same as a water park. The description of a water park is "An amusement area with water slides, recreational swimming pools and dressing rooms." Splash pads have none of these features. Splash pads vary in size, so a node or area can be used.
