White Sands National Park

White Sands protects 275 square miles of gypsum dunes, the largest field of its kind anywhere in the world. The dunes are a brilliant, almost blinding white, and they shift visibly as the wind pushes them slowly across the basin, so the shape of the place is never quite the same twice. Ringed by distant blue mountains, the dune field feels vast and quiet and utterly otherworldly, a landscape that surprises almost everyone who sees it for the first time.

The magic starts with the sand itself. Most sand is quartz, which soaks up heat, but gypsum reflects the sun and stays cool underfoot, which is why you can walk the dunes barefoot and why sledding down them feels so much like sledding on snow. A paved and packed-sand road called the Dunes Drive leads from the entrance into the heart of the field, where boardwalks and post-marked trails let you wander out onto the sand. The Interdune Boardwalk is an easy, accessible loop that everyone can enjoy, no matter their mobility.

This is a place ruled by light and sky. Midday turns the dunes dazzling white, but the finest hours come near sunset, when the sun paints the sand pink and orange and lays long blue shadows across the ripples. On clear nights the desert sky fills with stars above the pale glowing dunes, and a full moon can light the whole basin bright enough to walk without a flashlight. Few landscapes reward patience the way this one does.

• Main Entrance, off US-70 between Las Cruces and Alamogordo, is the one way into the park. It is open year-round, though the road and park close briefly, usually for a few hours at a time, when the surrounding missile range runs a test, so it is always worth checking access before you set out.
• From El Paso, Texas, take US-54 north to Alamogordo and then US-70 west, about a hundred miles in all. From Las Cruces to the southwest, US-70 climbs over San Augustin Pass and drops straight into the basin, about 55 miles. From Alamogordo the entrance is only about 15 miles west on US-70.

• The Dunes Drive is the heart of a visit, an eight-mile road that runs from the entrance deep into the dune field, where the pavement gives way to a road packed from gypsum itself, white between the dunes, with pullouts, picnic spots, and trailheads along the way.
• Sledding the dunes is the signature White Sands pleasure. Waxed plastic saucers slide beautifully down the smooth, firm dune faces. You can buy or rent a saucer at the park gift shop, then hike up a dune away from the road and glide down.
• The Interdune Boardwalk is a short, level, accessible loop that carries you out over the sand, with signs explaining the plants and creatures that survive in this strange white world.
• The Dune Life Nature Trail is a one-mile loop that climbs up into the dunes and shows how a few hardy animals and plants make a living here.
• The Alkali Flat Trail is a longer 4.6-mile loop that crosses the trackless white heart of the dune field, marked only by posts. It rewards careful, well-prepared hikers with total immersion in the dunes, and it demands real caution.

People have known these dunes for a very long time. Preserved in the old lakebed at the edge of the sand are fossilized human footprints that scientists have dated to roughly 21,000 to 23,000 years ago, near the height of the last ice age. They are among the oldest evidence of people anywhere in North America, and they sit alongside the tracks of ice-age giants, mammoths, giant ground sloths, and dire wolves, a snapshot of a wetter, greener basin long gone.

The basin has been home to Native peoples ever since. Its more recent history is tied closely to the Mescalero Apache, whose homeland reaches into the mountains just east of the dunes, as well as to the region's earlier Puebloan and ancestral peoples. Their long presence gives the white sands a human depth far older than the shifting surface suggests, and the park works with tribal communities to care for the places and stories held here.

Newcomers set the dunes aside as White Sands National Monument in 1933, and for decades visitors came to marvel at the strange white sea. In 2019 Congress redesignated it White Sands National Park, one of the newest national parks in the country. Along the way the surrounding basin became one of the most historic stretches of ground in the modern world.

The park sits within the vast White Sands Missile Range, established during World War II, and it lies not far from the Trinity site, where the first atomic bomb was tested in July 1945. Because the range is still active, the park occasionally closes for a few hours when tests are scheduled. That shared history is why the drive in passes a Missile Range Overlook and why the nearby town of Alamogordo grew into a center of American rocketry and spaceflight.

• The dunes are gypsum, not the quartz that makes most sand. Gypsum normally dissolves in water and almost never survives to form dunes, which makes White Sands one of the rarest landscapes on Earth.
• Because gypsum reflects sunlight instead of soaking it up, the sand stays cool to the touch even on a scorching day, which is why you can walk it barefoot.
• The dune field covers about 275 square miles and is the largest field of gypsum dunes anywhere in the world.
• Fossilized human footprints found at the park have been dated to around 21,000 to 23,000 years ago, some of the oldest known evidence of people in North America.
• The gypsum comes from a shallow, on-and-off lake called Lake Lucero, where water evaporates and leaves behind crystals of a mineral called selenite that the wind grinds into fine white sand.
• A few animals here have turned white to blend into the dunes, including a bleached earless lizard and a pale pocket mouse, an example of evolution you can see with your own eyes.
• White Sands became a national park only in 2019, after 86 years as a national monument, making it one of the youngest parks in the system.
• The park sits inside the active White Sands Missile Range, not far from the Trinity site where the first atomic bomb was tested in 1945.

• An entrance fee applies (per vehicle, good for several days); check the park website for current rates, and interagency annual passes are accepted.
• The park is open year-round, but it closes intermittently for military testing from the surrounding missile range, usually for a few hours at a time, so always check the schedule before you go.
• The Dune Life Nature Trail is an easy one-mile loop into the dune field, a good first taste of walking on the sand.
• The Alkali Flat Trail is a 4.6-mile loop across the white sand backcountry, marked by posts, so carry water, watch the weather, and note your landmarks.
• Backcountry camping requires a permit, and there is no water available out in the dunes, so pack in everything you will need.

White Sands is a national park in southern New Mexico, near the town of Alamogordo, that protects the largest gypsum dune field in the world, about 275 square miles of brilliant white sand rippling across the Tularosa Basin like waves of snow. Unlike ordinary sand, the gypsum stays cool to the touch, so you can walk it barefoot and sled down the dunes. It became a national park in 2019 after decades as a national monument, and it is one of the most surreal and beautiful landscapes in the country.

Yes, and it is one of the most popular things to do here. The smooth, firm dune faces are perfect for sliding on a waxed plastic saucer, which you can buy or rent at the park gift shop, along with wax to make it go faster. Regular sleds do not work well on the sand, so the special saucers are the way to go. Pick a dune away from the road, hike to the top, and glide down. It is a delightful, family-friendly experience that suits all ages.

Sometimes, yes. White Sands sits inside an active missile range, so the road into the park and the park itself close intermittently, usually for just a few hours at a time, when a test is scheduled. The closures are announced ahead of time, so it is always smart to check the park website or call ahead before you make the drive, especially if you are coming from far away. Plan your visit around the posted schedule and you will rarely be turned away.

The desert heat can be intense, and there is little to no shade or water out in the dunes, so carry plenty of water, wear sun protection, and go easy in the midday heat, especially in summer. The white dunes look alike in every direction, which makes it easy to get disoriented, so stay aware of where you are, note landmarks, keep track of your car, and do not wander far from marked areas on longer walks like the Alkali Flat Trail. A little preparation and awareness keep a visit safe and fun.

The Dunes Drive is the way to reach the dune field. It starts as pavement and then becomes a road packed from the gypsum itself, which most cars handle fine when you drive slowly and stay on the roadway. There are marked parking areas and pullouts along the drive where you leave your car and walk out onto the sand. Avoid pulling off onto the soft, loose sand at the edges, where vehicles can get stuck, and follow the posted signs.

Fall, winter, and spring bring the most comfortable temperatures for exploring the dunes, while summer is very hot, so early morning or evening is best then. The finest light of all comes near sunset, when the low sun paints the white sand gold, pink, and orange, and full-moon nights can light the whole basin beautifully. For the best mix of pleasant weather and gorgeous light, aim for the cooler months and the golden hours around sunrise and sunset.

Yes. White Sands charges a per-vehicle entrance fee that is good for several days, and interagency annual passes are accepted. Check the National Park Service website for the current rate before you go.

You can drive the Dunes Drive, walk a boardwalk, and get a good feel for the dunes in a half day. To hike a trail, do some sledding, picnic, and stay for the sunset without rushing, give it most of a day. Many visitors time their trip so they arrive in the afternoon and stay through the golden hour, which is when the dunes are at their most magical.

Yes, White Sands is fairly pet-friendly. Leashed pets are welcome on the Dunes Drive and out on the sand in most areas, which is unusual among national parks. Just remember there is no shade and the surface can get warm at midday, so bring water for your dog, watch their paws, and never leave a pet in a parked car. Check the park website for the current pet rules before you visit.

There is no lodging inside the park, and camping is limited to permitted backcountry sites out in the dunes with no water. Most visitors base themselves in Alamogordo, about 15 miles east, which has the widest choice of places to stay, or in Las Cruces to the southwest. Both make an easy day trip to the dunes, and staying nearby lets you catch both a sunset and an early-morning visit before the heat builds.
