National Park Service, Colorado.
Open all day and night year round, the tallest dunes in North America are the centerpiece in a diverse landscape of grasslands, wetlands, conifer and aspen forests, alpine lakes, and tundra. Experience a starry sky on moonless nights, or a surreal walk on the dunes under bright full moonlight.
To access the main park area, including the Dunes Parking Lot, Visitor Center, and Pinon Flats Campground, take US 160 to CO 150 from the south, or CO 17 to Lane 6 to CO 150 from the west. The national park is at the north end of CO 150.
