This theme park is one of four theme parks at the Walt Disney World Resort and opened on Oct. 1, 1971.

The Magic Kingdom is divided into five distinct areas or lands all meeting at the top of Main Street U.S.A. right in front of Cinderella Castle. These are names as Tomorrowland, Fantasyland, Frontierland, Liberty Square and Adventureland. Each land is themed to its appropriate title and maintaining that theme is paramount to the parks operation. A Big network of underground tunnels connect all areas of the Magic Kingdom. You will never miss Space Mountain which is one of the best attractions at the Magic Kingdom.

In the words of Roy O. Disney, "Walt Disney World is a tribute to the philosophy and life of Walter Elias Disney... and to the talents, the dedication, and the loyalty of the entire Disney organization that made Walt Disney's dream come true. May Walt Disney World bring Joy and Inspiration and New Knowledge to all who come to this happy place ... a Magic Kingdom where the young at heart of all ages can laugh and play and learn — together."
