Great Sand Dunes National Park and Preserve

Great Sand Dunes National Park and Preserve protects the tallest sand dunes in the USA, rising up to 750' and covering some 30 square miles. It has only been a National Park since 2004; before that was a National Monument since 1932. Bounded on the east by the rugged Sangre de Cristo mountains, the dunes make a stunning picture.
