Douglas County, Colorado
Douglas County is located between Denver and Colorado Springs in the heart of Colorado’s Front Range. Castle Rock serves as the county seat and has experienced rapid growth along with the surrounding region. The county is known for its high incomes and extensive residential development.
The eastern part of Douglas County remains more rural, with ranches, open spaces, and undeveloped land, while Pike National Forest covers portions of the western edge. The county reflects a mix of suburban growth and efforts to preserve its agricultural and Western heritage.
