What to Do at White Sands National Park: The Dunes Drive, Sledding, and Sunsets

White Sands National Park sits in the Tularosa Basin of southern New Mexico, a sea of brilliant white gypsum sand covering about 275 square miles, the largest dunefield of its kind on Earth. Redesignated from a national monument to a national park in December 2019, it is a compact, unusual place: almost everything you come to do happens along one eight mile road and on the dunes beside it. You can drive into the heart of the sand in twenty minutes, sled down a dune, walk a trail into blinding white, and stay for a glowing sunset.

Best fit

Travelers who want a short, high impact stop: a couple of hours to half a day playing on the dunes, easy to fold into a New Mexico road trip between Alamogordo, Las Cruces, and El Paso. Families come for the sledding, photographers for the light.

Start here

Stop at the visitor center for a sled, the day's road hours, and any missile closure times, then drive the eight mile Dunes Drive to the loop at the end, where the pavement gives way to packed gypsum and the dunes are highest.

Skip if

You need shade, water, or food inside the park, because there is none, or you cannot handle midday summer heat that regularly tops 100 degrees. In summer, come early or for sunset rather than the middle of the day.

Decision system

The planning sequence

Use the sequence below to decide how this should shape the trip.

What to doWhat it isPlanning note

Drive the Dunes DriveThe eight mile scenic road from the visitor center into the tallest dunes, sixteen miles round trip, with pullouts, picnic shelters, and trailheadsAllow an hour at a minimum. The final stretch is hard packed gypsum, drivable in a normal car; watch for soft sand on the shoulders.

Sled the dunesSliding down the steep faces of the gypsum dunes on a plastic saucer, the park's signature activityBuy and wax a saucer at the gift shop and sell it back after, or bring your own. Sled well away from the road, on the far side of the dunes.

Interdune BoardwalkA short raised boardwalk, about four tenths of a mile, with panels on the plants and animals that survive in the gypsumThe easy, accessible option, good for a first look and for anyone not up for walking on loose sand.

Dune Life Nature TrailA one mile loop marked by posts that climbs into the older, plant covered dunes at the edge of the fieldFollow the numbered markers carefully; footprints vanish fast and it is easy to lose the route in the sand.

Alkali Flat TrailA roughly five mile round trip across open dunefield to the edge of the dry bed of ancient Lake OteroThe park's big hike. No shade and no water, marked only by posts; carry water and turn back in heat or high wind.

Sunset and night programsRanger led sunset strolls, summer full moon evenings, and monthly caravan tours to Lake Lucero, the source of the gypsumThese run on a set schedule and some need reservations; check the park calendar before you go.

1Before you go: Check the park calendar for missile test closures, which can shut US Highway 70 and the park for up to a few hours, and note the day's road hours. There is no fuel, food, or reliable cell service inside, so fill up and stock water in Alamogordo first.

2Late afternoon: Start at the visitor center, a 1930s adobe building with exhibits, water, restrooms, and the gift shop where you buy and wax a sled. Current hours and any closures are posted here.

3Golden hour: Drive the eight mile Dunes Drive to the loop at the end, where the dunes are tallest and the pavement turns to packed gypsum, and pick a dune away from the road for sledding.

4Sunset: Walk a short way onto the dunes, or take the Interdune Boardwalk, and stay for the light. The white sand goes pink then blue as the sun drops behind the San Andres Mountains.

5With a full day: Add the Alkali Flat Trail in the cool of the morning, carrying plenty of water, and time your visit around a ranger led sunset stroll or a full moon night.

The dunes

Gypsum, not the usual sand

White Sands is not quartz beach sand but gypsum, a soft mineral that rarely reaches the surface because it dissolves in water. Rain and snowmelt wash gypsum out of the surrounding mountains into the Tularosa Basin, a valley with no outlet to the sea, where it collects in the dry bed of ancient Lake Otero and dries into crystals that the wind grinds into dunes. Because gypsum reflects sunlight rather than absorbing it, the sand stays cool underfoot, which is why you can walk and sled barefoot where other deserts would burn.

Getting there and getting in

White Sands lies just off US Highway 70 between Alamogordo, about fifteen miles to the northeast, and Las Cruces, about an hour to the west. The nearest airport with major service is El Paso, Texas, roughly ninety miles south. The park has one entrance and one road in, the Dunes Drive, so base yourself in Alamogordo for lodging, food, and gas, none of which exist inside the park. Because the dunes sit within the White Sands Missile Range, the park and the highway sometimes close for missile tests, so check the park calendar the morning you go.

Sledding and the Dunes Drive

The heart of a visit is simple: drive in and slide down the sand. The gift shop at the visitor center sells plastic snow saucers and wax, and buys the saucers back when you leave, so most people need not bring their own. Drive to the far end of the eight mile road, where the dunes are highest and the loops sit against them, then walk over the first ridge to sled the steeper faces away from traffic. Waxing the base makes all the difference on gypsum, which grips more than snow.

Walking into the white

Beyond the boardwalk, three marked trails let you leave the road behind. The Interdune Boardwalk is a short, flat, accessible loop with signs; the Dune Life Nature Trail is a one mile loop into the older, plant covered dunes; and the Alkali Flat Trail is the serious one, about five miles round trip to the edge of the old lakebed. All are marked by numbered posts, not worn paths, because footprints fill in within hours, so keep the next marker in sight. Carry more water than you think you need, and avoid the open routes in midday heat or high wind.

Sunsets, full moons, and Lake Lucero

Sunset is the best hour at White Sands, when the crowds thin, the temperature drops, and low light turns the dunes pink and violet against the mountains. Rangers lead sunset strolls, and on summer full moon nights the park stays open late for stargazing. About once a month, conditions permitting, rangers guide a caravan out to Lake Lucero, the dry lakebed where the gypsum crystals form, a trip you cannot make on your own. These programs fill quickly, so book through the park before you arrive.

Planning traps

Mistakes to avoid

These are the small decisions that quietly derail an otherwise good plan.

1. Going in the middle of a summer day

From late spring through summer the basin regularly climbs above 100 degrees, and the open dunes offer no shade at all. The sand stays cool, but you will not. Come in the early morning or, better, for the last few hours before sunset, when the heat breaks and the light is at its best. Always carry water, since the park sells none out on the drive.

2. Forgetting to check for missile closures

White Sands sits inside an active missile range, and the park and US Highway 70 can close for a couple of hours during tests. The closures are posted in advance on the park calendar and announced at the gate, but travelers who do not check can lose a chunk of their day or their route. Look up the schedule the morning of your visit and build in some slack.

3. Treating the dunefield like a marked beach

The trails are marked by posts, not paths, and your own footprints disappear within hours as the sand shifts. People wander off the markers to chase a photo and lose their bearings in a landscape with few fixed references. Stay within sight of the next post, especially on the Alkali Flat Trail, and turn back if wind erases the route or the heat builds.

FAQ

Common planning questions

What is there to do at White Sands National Park?

Drive the eight mile Dunes Drive into the tallest dunes, sled down the gypsum on a plastic saucer, walk a marked trail such as the Interdune Boardwalk or the longer Alkali Flat Trail, and stay for sunset. Rangers also lead sunset strolls, full moon nights, and monthly tours to Lake Lucero, the source of the sand.

Can you sled at White Sands?

Yes, sledding down the dunes is the park's signature activity. Bring a plastic snow saucer or buy one at the visitor center gift shop, which also sells wax and buys saucers back when you leave. Wax the base, drive to the tall dunes at the end of the road, and sled the steep faces away from traffic.

How much time do you need at White Sands?

A couple of hours is enough to drive in, sled, and walk a short trail, which is why many people stop here on the way between Alamogordo and Las Cruces. To add the Alkali Flat Trail or a ranger led sunset program, plan on half a day or an evening.

What are the closest town and airport to White Sands?

Alamogordo, New Mexico, is about fifteen miles northeast and is where most visitors find lodging, food, and gas, since there is none in the park. The nearest airport with major airline service is El Paso, Texas, roughly ninety miles to the south.

Is the sand at White Sands made of sugar or salt?

Neither. It is gypsum, a soft white mineral washed out of the surrounding mountains into a basin with no outlet to the sea, where it dries and the wind grinds it into fine sand. Because gypsum reflects sunlight instead of absorbing it, the dunes stay cool enough to walk on barefoot.
