Kennywood opened its official waterpark in 1989 on land formerly occupied by U.S. Steel’s Homestead Works. The park has a picturesque riverside setting on the shore of the Monongahela, five miles downstream from Kennywood. In addition to the standard waterpark fare, the adjacent RiverPlex offers a peaceful, wooded picnic area.
