Located far from any ocean, the 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 20 miles long and 5 miles wide and range from 50 to 400 feet high. This 10,600-acre playground of shifting, white quartz sand is known for its unique beauty and exceptional space for off-highway vehicle (OHV) enthusiasts, hikers and equestrians.
