Explore and Ride St. Anthony Sand Dunes in Idaho

Located far from any ocean, the BLM-managed St. Anthony Sand Dunes appears as a rolling sea of sand on the eastern edge of Idaho’s volcanic Snake River Plain. These vast dunes are the largest in Idaho. They blanket an area approximately 35 miles long and 5 wide, and range from 50 to 500 feet high. These white quartz sand dunes are a unique and popular recreational playground for off-highway vehicle enthusiasts, hikers and equestrians. Picnicking, snowmobiling, wildlife viewing and camping opportunities are also available here. The area features Deadhorse Bowl, a popular OHV sand bowl one-mile in circumference and 400 feet deep, located in the western section of the dune complex.
