Welcome to Castle Rock
Named for the prominent castle-shaped butte in the center of town, Castle Rock is the southernmost town to be considered a Denver suburb. Homesteaders first came to the area in the mid 1860s to search for gold, but it was ultimately the discovery of ryholite stone—a volcanic rock used as an aggregate in the construction industry—that led to its settlement. In 1874, a homesteader donated 120 acres and the town of Castle Rock was formed. Downtown Castle Rock marries small-town charm, eclectic shops and restaurants, and breathtaking scenery. And if the boutiques and specialized services offered there aren’t your speed, you’re sure to find what you’re looking for at the Outlets at Castle Rock—the largest open-air outlet center in the state of Colorado. Castle Rock takes full advantage of its gorgeous natural setting, with 27% of the town’s total land area dedicated to open space and parks. It has repeatedly been included on “Best Town” lists in Money, Family Circle, and Forbes magazines based on its top-rated schools, home affordability, safety and quality of life.
