The Great Sand Dunes National Park and Preserve lies nestled against the shoulder of the Sangre de Cristo mountains in southern Colorado, a surreal, deep desert landscape hidden in the American West.
Approaching from the south, the dunes first appear as haze at the foot of the snowcapped peaks. It’s only when much closer, entering the park on Highway 150, that the sheer scope becomes apparent—30 square miles of sand, with the tallest dunes topping 700 feet.
