Just a few miles north of Rock Springs, Wyoming, lies a dream world wherein the hills sing. Literally. It’s a strange and beautiful natural wonder known as the Killpecker Sand Dunes, and there, the hills are most certainly alive with the sound of music.

Stretching for miles east of the Green River Basin, these perfect rows of sand have been sculpted by wind for tens of thousands of years.

The individual grains of sand here are rounded and smoother than the average grain; this unique set of circumstances allows the dunes to “boom”, or sing, when wind flows over them.

Spanning 55 miles, the pearlescent dunes seem to extend forever, and the beautiful, eerie singing interrupts the otherwise tranquil stillness of the Wyoming Red Desert. It is equal parts beautiful and unsettling.

There is no cost to explore the dunes; one can make it a simple day trip, or they can camp in the area if they’d like to. The days are warm and mild in the summer, and during the winter, one can expect dustings of snow.

Jutting 400 feet above the sandy landscape, the skeletal remains of an ancient volcano contribute to the seemingly alien terrain.

Hikers and sportsmen alike look for this fantastic monument to orient themselves in this vast, bizarre place, where getting lost is easy.

Despite the appearance of being a desert wasteland, these mysterious singing dunes are teeming with life.

Desert grass is sprinkled at random over the countless miles of dunes, some of which reach up to 15 feet tall.

Amazingly, this incredible natural wonder is the second largest active dune on planet Earth! An “active” dune is a dune that is in a constant state of building and change.

To seek out this strange land for yourself, travel northbound on State Highway 191 from Rock Springs, Wyoming. Turn right on County Road 4-17/Tri-Territory Loop Road and follow it for about 20 miles. Once you come upon the Sand Dunes access road, take it, and follow it for one mile. Hang a right at the intersection you’ll arrive at, and drive just one more mile to the campground. Remember: leave no trace! What you pack in, make sure to pack out so that future generations can appreciate this incredible natural wonderland.
