Great entertainment value for the Waterloo, Cedar Falls area. Well maintained and it seems ever year a new attraction is added. The park is clean, always fully staffed with life guards, it is a all round great family get a way. As a bonus for those of us who live in the area, they offer a season pass which is in my opinion very reasonable.
