The Town of Castle Rock is named after Rock Park, a historic natural landmark and perhaps the most visible open space property in Castle Rock. Since 1935, this important landmark has been famous for the annual starlighting ceremony. Rock Park became the first open space parcel in Town when concerned citizens fought for its protection from development in 1988. Through the dedication of many volunteers, including Keepers of the Rock in partnership with Castle Rock Teen Court, Wildlands Restoration Volunteers, Eagle Scouts and local residents, this property and its trails have undergone numerous restoration and improvement projects over the years.
