National Park Service, Colorado.
Open 24/7 year round! There are no limitations or reservations to visit, but there is currently limited capacity in the visitor center. The tallest dunes in North America are the centerpiece in a diverse landscape of grasslands, wetlands, forests, alpine lakes, and tundra. Stay on a moonless night to experience this International Dark Sky Park's starry skies!
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.
