Cobblestone Ranch
By Jessica Carcoana · Updated September 2026
Richmond American Homes has built Cobblestone Ranch on Castle Rock's northeast edge near Parker since 2006, two-story and ranch plans on 5,000 to 7,000 square foot lots with basements standard. The 12-acre Cobblestone Ranch Park at 8571 Castle Oaks Drive adds six pickleball courts, a bike skills zone with asphalt and wood ramps, and two playgrounds split by age group, with a paved trail connecting to the neighboring Arabella section. More than 600 acres of open space separate the community from surrounding development, and Founders Parkway carries traffic to I-25 in about eight minutes.
