Pikes Peak, a thousand-foot slot canyon, and North America's tallest dunes
Colorado Springs to Cañon City to Alamosa is a 200-mile arc through some of the most dramatic terrain in the lower 48. The Royal Gorge Bridge (1929) spans a 1,053-foot slot in granite — the world's highest suspension bridge for 72 years. The Great Sand Dunes pile to 750 feet against the wall of the Sangre de Cristos in the San Luis Valley.
