Great Sand Dunes National Park
Introduction
Great Sand Dunes National Park sits in Colorado's San Luis Valley with the tallest dunes in North America — over 230 m high, built by wind from ancient dry lake beds, backed by the snowy Sangre de Cristo Mountains for a surreal sand-meets-snow scene. The dunes shift between gold, orange and grey with the light, most dramatic at sunrise and dusk. In summer, Medano Creek spreads into a shallow stream at the base for kids to play; in spring and autumn strong winds ripple the surface like waves. It's a hub for sandboarding, hiking and night-sky photography, and one of the few wild places where desert, high peaks, lake and wetland share one frame.
