Is the sand really as cool and soft as people say?

Yes. Unlike quartz sand, gypsum does not absorb and hold heat the same way, so even on a 95°F afternoon the surface of the dunes stays relatively cool to the touch — often cooler than the air a foot above it. The grains are also very fine and round, so it feels closer to powdered sugar than to beach sand. It does get into everything, however; zip-top bags for your phone and camera are genuinely useful.

Why does US-70 close, and how do I check?

White Sands National Park is surrounded by White Sands Missile Range, which periodically tests ordnance that passes over the park and the highway. When that happens, rangers close both the park and US-70 for 1 to 3 hours at a time, usually with a few days' notice. Check the park's alerts page on nps.gov/whsa or call the visitor center the day before and the morning of your visit. Plan with a little buffer so a closure doesn't wreck your sunset.

Are there any restrictions on dune sledding or hiking off-trail?

Sledding is allowed anywhere off the road except on vegetated dunes, and you must yield to anyone hiking. Off-trail hiking in the dunes themselves is fine and encouraged — the gypsum is durable and your tracks disappear with the next wind — but it is genuinely easy to get lost once you're out of sight of the road, since the dunes all look similar and there are no obvious landmarks. Use the marked trails until you're confident, and always carry a GPS or compass past the first ridge.

Is White Sands good for kids?

Very. The short trails are stroller-accessible or easy for small legs, the sledding is a universal hit, and the park's Junior Ranger program at the visitor center is one of the better ones in the Southwest. Bring sun protection — hats, long sleeves, sunglasses, and kid-strength sunscreen — because the reflected light off the gypsum is intense and sunburns can sneak up fast. Water bottles for every family member are non-negotiable, even on short walks.

White Sands

A New Mexico park of dazzling white gypsum dunes — the world's largest gypsum dunefield — creating a landscape that appears to be snow even in summer heat.

Overview

White Sands National Park protects 275 square miles of brilliant white gypsum dunes in the Tularosa Basin of southern New Mexico — the largest gypsum dunefield on Earth and the only one in the world big enough to be visible from space. Unlike the quartz sand of most deserts, gypsum is soft, cool to the touch, and almost blindingly white, which is why your brain spends the first hour here quietly insisting the ground is covered in snow even as you stand there in shorts. The park was redesignated from a national monument in 2019, and its footprint is deceptively compact. The entire dunefield sits about 15 minutes from Alamogordo, a single paved road — the eight-mile Dunes Drive — loops through the heart of it, and a handful of short, flagged trails head into the backcountry from pullouts along the loop. You could check the box on White Sands in an afternoon. You shouldn't. The park's magic is entirely a function of light — late-afternoon shadows stretching across the ridges, a full moon rising over the San Andres Mountains to the west, the gypsum glowing pink for about 12 minutes at sunset — and planning your visit around it turns a short stop into the most memorable two hours of a New Mexico trip. Bring sunglasses, closed-toe shoes, and twice the water you think you'll need.

What to See & Do

Dune sledding on the white gypsum slopes (buy a sled at the gift shop)

The soft, compacted gypsum makes for some of the best downhill sliding outside of a ski resort — and the park's gift shop sells round plastic snow saucers for around $20 (plus a few dollars for a block of dune wax that makes them fly). Pick a steep face along Dunes Drive, wax the bottom of your sled, and go. Kids are the obvious market here, but plenty of adults pick up a sled and never stop laughing. Used sleds can be bought back at 50% when you leave. Avoid the hottest part of the day — midsummer sand temperatures exceed 100°F even though the gypsum feels cool.

Alkali Flat Trail — a 5-mile loop deep into the dunefield

The Alkali Flat Trail is the park's longest marked route — a 5-mile loop flagged by red-topped posts that winds from the Dunes Drive's end out to the dry bed of Lake Otero and back. You are in open, unshaded, featureless terrain the entire way, and it's easy to lose track of the trail if the wind has erased tracks or a post has tipped. Start before 8 a.m. in any season except winter, carry at least three liters of water per person, wear real hiking shoes, and turn around immediately if thunderstorms appear — there is no shelter out there. It's a moonscape hike unlike anything else in the national park system.

Sunset stroll on the Dunes Drive for golden-hour photography

An hour before sunset, pull into any of the picnic-area loops along Dunes Drive — Primrose, Yucca, or Sunset Stroll — and walk a few hundred yards off the road into the dunes. The low-angle sun throws long, sharp shadow ripples across the gypsum, the sky pinks up behind the San Andres, and the whole basin turns color for about 15 minutes. This is the single best photograph-the-park time, and the park stays open roughly an hour after sunset so you can wait out the light. Bring a headlamp for the walk back to the car.

Heart of the Dunes nature trail through the dunefield

The 1-mile Dune Life Nature Trail, toward the east end of Dunes Drive, is the short self-guided loop that introduces you to the surprisingly rich gypsum ecology — bleached earless lizards that evolved their pale color to blend in, soaptree yucca stalks holding their crowns above rising dunes, and kangaroo rat burrows under the ripples. Interpretive signs explain the geology of how the dunes form when gypsum-laden runoff from the San Andres evaporates in Lake Lucero. It's the best half-hour introduction to the park you can get, and doable with small kids and grandparents.

Interdune Boardwalk through the ecology of gypsum dunes

The 0.4-mile Interdune Boardwalk is the park's fully accessible, elevated wooden walkway, running from a Dunes Drive pullout out into the heart of an interdunal flat. Interpretive panels every 30 feet cover everything from the park's White Sands pupfish to the gypsum selenite crystals that seed each dune. It's an ideal stop for wheelchair users, stroller families, or anyone who wants to understand what they're looking at before committing to a longer trail. Do it in the first hour after the gates open; by midday the boardwalk deck gets hot and shadeless.

Full moon night programs and stargazing events

A full moon over White Sands is one of the strangest and most beautiful nights you will ever spend outdoors — the gypsum reflects so much light that the dunes read silver, headlamps become unnecessary, and your own shadow walks with you across the sand. The park runs ticketed Full Moon Hikes and Full Moon Nights events in the warmer months; tickets sell out fast on Recreation.gov. Off-season, the park's certification as part of a dark-sky corridor means new-moon stargazing from the amphitheater is excellent — bring warm layers, since the basin cools fast after dark.

Backcountry camping in the white dune wilderness

Ten primitive backcountry campsites sit about a mile's walk off Dunes Drive in the dunefield — no water, no shelter, no facilities of any kind, just a marker post in the sand and the biggest sky you've ever slept under. Permits are issued in person at the visitor center on a first-come basis the day of your stay and cost $3 per person. You need a tent you trust to stake out in loose gypsum, three liters of water per person per night, and a willingness to navigate to and from your site in the dark. It's one of the most surreal overnights in the park system.

Getting There & When to Go

The park sits just off US-70 between Alamogordo (15 miles east) and Las Cruces (50 miles west). El Paso International Airport, 90 miles south, is the main commercial gateway; Albuquerque is about 3.5 hours by car to the north. One important quirk: US-70 through the park closes periodically — usually for 1 to 3 hours — for missile tests at the adjacent White Sands Missile Range, so always check the closure schedule before you go. October through April is prime season, with daytime highs in the 60s and 70s°F and cool nights; May through September is hot, though sunset and early-morning visits still work well. Flash-flood-producing thunderstorms are common July through September.

Where to Stay

There is no lodging inside the park and no developed campground, so base yourself in Alamogordo, 15 minutes east, where the Fairfield Inn, Hampton Inn, and a cluster of midrange hotels offer the most convenient access — you can be at the gate 20 minutes after breakfast. Las Cruces, 50 miles west, has a wider range of hotels and restaurants and pairs well with a broader southern New Mexico trip including Organ Mountains-Desert Peaks. A handful of small RV parks and campgrounds sit along US-70 between the park and Alamogordo. For a backcountry overnight inside the park, the 10 primitive dune sites are the only option and require a same-day walk-up permit.
