The dunes at Bruneau Dunes State Park – rising 470 feet at the peak – are unique in the Western Hemisphere, where they form at the center rather than the edge of a natural basin. Sandboards to sled down the dunes are available for rent, or you can hike or go horseback riding around the park to investigate the Idaho desert.
