Great Sand Dunes National Monument
Nestled against the Sangre de Cristo Mountains of southern Colorado, North America's tallest sand dunes rise 700 feet from the desert floor of the San Luis Valley. Volcanic sediments, washed from the San Juan Mountains by the headwaters of the Rio Grande River, are the tiny building blocks which create these fantastic, wind-shaped geological features.
Visitors can hike the dunes and several nature trails, observe plants and animals and camp at either a campground near the dunes or in the backcountry. Medano Creek, which flows at the base of the dunes during spring and early summer, allows for sand castle building, fishing and hiking.
