Tucked away in the north part of the park, accessible only by tens of miles of dirt road, these are the second tallest dunes in the United States. Don’t let their out-of-the-way location deter you from visiting, however. The solitude only adds to the otherworldliness of the wind-swept sands, the highly rare Eureka Grass blades grasping for life in the dry mounds, and the panoramic view of the colorful Last Chance and Saline Ranges which flank the dunes on either side.
