History- Castle Rock was incorporated in 1881, situated between the big plains and the foothills of the Rocky Mountains, shielded from the worst winter storms. The area surrounding Castle Rock was a well suited location for the Arapahoe and Cheyenne Indians and the wild game, such as buffalo, antelope, and deer, which they sought for food.

Jeremiah Gould was one of the original homesteaders. He owned 160 acres to the south of “the rock.” The community at this time consisted of a few shacks for prospectors, quarry workers and other hired hands. In 1847, after Castle Rock officially became designated the seat of Douglas County, Gould donated 120 acres to “be known as Castle Rock.”

Recreation- Castle Rock is home to a town recreation center that is "private club" quality. In addition Castle Rock has numerous baseball and softball fields with playgrounds and picnic areas, swimming pools, world class golf courses, numerous public and private tennis courts and bike paths.

During all times of the year, the Castle Rock Recreation Department conducts recreational leagues in many different sports, including basketball, volleyball and softball. There are also ongoing recreational activities for everyone from preschool to senior participants.
