Sand dunes provide wonderful recreational opportunities and scenery in this vast region.
Wyoming’s popular Killpecker Sand Dunes, in the Red Desert, should not be missed. From Rock Springs, travel north on U.S. Highway 191 approximately 10.5 miles and turn east (right) onto the Tri-Territory Road (County Road 4-17, also known as Chilton Road). Killpecker Sand Dunes is 28 miles from Rock Springs, and features one of the largest active sand dunes in North America. Some of the dunes are more than 100-feet tall. Running for one hundred miles west to east, the landscape is constantly shifting as winds buffet the dunes. The Killpecker Sand Dunes are a popular place for both hikers and off-road vehicle enthusiasts. Many ATVers also use the dunes, where the BLM has opened 13,000 acres to off-road vehicle use. Open play is permitted in certain areas; others are closed to vehicles to protect important deer and elk birthing grounds and wilderness study areas.
In southwestern Idaho, pay a visit to Bruneau Dunes State Park, where you can see the continent’s tallest single sand dune rising more than 470 feet above the desert floor. You can also enjoy a number of recreational opportunities.
The St. Anthony Sand Dunes are about eight miles west of the town of St. Anthony, in eastern Idaho. The white, rolling hills of sand rise 200 to 300 feet above the valley floor, and stretch about 35 miles in length.
