Castle Rock, CO

Castle Rock straddles I-25 between Denver and Colorado Springs, making it a natural pit stop for Front Range travelers. The city sits at 6,200 feet where the high plains meet the foothills, centered around the iconic sandstone butte that gives it its name. Most visitors arrive via I-25, though Highway 85 runs through the historic downtown area. The 200-foot Castle Rock formation served as a landmark for pioneers on the Cherokee Trail and remains the town's most recognizable feature.
