Dutch Wonderland Family Amusement Complex was opened in 1963 by the Clark family from Lancaster County, Pennsylvania. The park started with 14 acres of land, four rides, and 18 employees. Over the years, Earl E. Clark expanded the family amusement park to include the Discover Lancaster County History Museum and the Old Mill Stream Campground. In November 2001, the complex was purchased by Hershey Entertainment & Resorts Company. The park is presently owned and operated by Wonderland Amusement Management LLC, a wholly owned subsidiary of Hershey Entertainment & Resorts Company.
