White Sands National Park

White Sands National Park protects the largest gypsum dunefield in the world — a dazzling, otherworldly sea of pure white sand that rolls in great waves across 275 square miles of the Tularosa Basin in southern New Mexico. Unlike ordinary quartz sand, these brilliant white dunes are made of fine gypsum crystals, cool to the touch even under the desert sun, and they shift and glow with extraordinary beauty.

Visitors drive the Dunes Drive into the heart of the dunefield to hike marked trails, sled down the slopes on waxed discs, picnic among the dunes, and witness spectacular sunrises and sunsets when the sand turns gold, pink and lavender. Surrounded by the missile range that tested the first atomic bomb, and dotted with hardy plants and specialized white-adapted wildlife, White Sands is a surreal landscape and a treasured natural icon of New Mexico.

Visitors drive the eight-mile Dunes Drive into the heart of the dunefield, then hike the marked trails (from the easy Playa and Dune Life trails to the strenuous Alkali Flat Trail across the open dunes), sled down the white slopes on waxed plastic discs (sold at the gift shop), picnic at the shaded sites, and camp in the backcountry dunes. Photography, sunset-watching and sledding are signature draws. The combination of the dazzling white dunes, the sledding and the unforgettable sunsets makes White Sands a uniquely playful and beautiful destination.

Fall, winter and spring offer the most comfortable temperatures for exploring the dunes, while summer days are very hot (though the gypsum sand stays cool). Sunrise and sunset are the magical times, when the low light turns the white sand gold and rose and the shadows ripple across the dunes; full-moon nights are sublime. The park occasionally closes for missile tests on the adjacent range. Cooler seasons and the golden hours are the highlights — come for sunset, and check the park’s schedule for any test-related closures before visiting.

The Tularosa Basin has been home to people for thousands of years, from ancient hunters who left footprints in the gypsum to the Mescalero Apache and others. The dunes were protected as White Sands National Monument in 1933 and redesignated a national park in 2019. The surrounding missile range was the site of the Trinity Test, the first detonation of an atomic bomb, in 1945. Recently, fossilized human footprints in the basin have pushed back the known story of people in the Americas. White Sands preserves this surreal landscape and its deep human history, a treasured icon of New Mexico.

White Sands is made of gypsum, a soft mineral rarely found as sand because it dissolves in water — but in the enclosed Tularosa Basin, gypsum washed from the surrounding mountains has no outlet to the sea, collecting in an ancient lakebed (Lake Otero) and the playa of Lake Lucero. As the water evaporates, the gypsum crystallizes and weathers into fine white grains that the prevailing winds pile into the vast dunefield, ever shifting and growing. The enclosed basin, the trapped gypsum and the wind created the largest gypsum dunefield on Earth.

Life at White Sands has adapted in remarkable ways — several animals here have evolved white or pale coloring to blend with the gypsum, including a bleached earless lizard, the Apache pocket mouse and certain insects, while the dunes also shelter kit foxes, coyotes, badgers, rodents and a variety of reptiles, and the surrounding desert hosts birds and other wildlife. Hardy plants like soaptree yucca and skunkbush sumac survive by growing pedestals atop the dunes. This unusual ecosystem of white-adapted creatures makes White Sands a fascinating place for wildlife observation.

The park protects a unique gypsum-dune ecosystem — a harsh, shifting world of pure white sand where only specially adapted plants and animals survive, including the famous pale, gypsum-camouflaged species found nowhere else. Hardy plants stabilize parts of the dunes; the interdune flats and the playa support their own life. The ecosystem is shaped by the constant wind, the lack of water and the brilliant reflective sand. Protecting this fragile, specialized dunefield, its adapted wildlife and its plants sustains both the ecology and the surreal beauty of White Sands.

White Sands holds a treasured place among the natural icons of New Mexico and the nation — a surreal, dazzling landscape unlike any other, beloved for its beauty, its sledding and its unforgettable sunsets, and recently elevated to national-park status. Steeped in deep human history, from ancient footprints to the dawn of the atomic age on the adjacent range, the dunes embody the strange grandeur of the desert Southwest. White Sands is a cherished icon of New Mexico and one of the most distinctive landscapes in America.

White Sands National Park is in southern New Mexico, off U.S. 70 between the towns of Alamogordo and Las Cruces, with the entrance and visitor center at the edge of the dunefield. An entrance fee applies. The Dunes Drive leads into the dunes to trailheads, picnic areas and sledding slopes; the visitor center sells sleds and offers exhibits. The park and highway occasionally close for missile tests on the adjacent White Sands Missile Range. There is no developed campground (backcountry only, when available). Check the National Park Service for fees, hours, sunset times and closure schedules before visiting.

The National Park Service protects the fragile gypsum dunefield and its specialized life. Visitors help by staying off the vegetation and the fragile interdune areas, packing out everything, not removing the gypsum sand, sledding only on open dunes away from plants, carrying plenty of water, and following all rules. The dunes are constantly shifting, and trail markers are vital — staying oriented protects both visitors and the landscape. Protecting the dunes, the adapted wildlife and the plants sustains both the ecology and the surreal beauty of this one-of-a-kind landscape.

The open dunes can be disorienting — stay near marked trail posts, never wander out of sight of them, and carry plenty of water, sun protection and a charged phone, as it is easy to get lost and there is no shade. Summer heat is dangerous despite the cool sand. Sudden afternoon winds can cause whiteout-like conditions. Sled only on open slopes away from roads, plants and other people, and not headfirst. Watch for the park’s closure schedule for missile tests. Respect the heat, the disorientation risk on the open dunes, and the need for water and navigation.

An entrance fee applies. Stay on marked trails and keep trail posts in sight on the open dunes. Do not disturb or remove the gypsum sand or harm the vegetation. Sled only in designated open areas, away from the road, plants and people. Pets must be leashed. Drones are prohibited. Backcountry camping requires a permit (when available). Glass containers are discouraged. The park may close for missile tests — obey all closures. Pack out all trash. Check the National Park Service for fees, sledding rules, closure schedules and current regulations before visiting.

The towns of Alamogordo (with its space history museum) and Las Cruces, the Organ Mountains, the Mescalero Apache lands and the mountain town of Cloudcroft, and the vast White Sands Missile Range lie near the park. The Tularosa Basin and the surrounding mountains define the region. White Sands anchors a remarkable region of southern New Mexico, a centerpiece of a Southwest adventure, easily combined with the Organ Mountains, the mountain village of Cloudcroft and the space-history sites at Alamogordo.

Come for sunset — the white dunes turn gold, pink and lavender and the experience is unforgettable (check the park’s posted sunset time and stay-after-dark rules). Buy or rent a waxed plastic sled at the visitor center and find an open slope away from plants. Bring lots of water, sun protection and a hat (there is no shade), wear shoes that handle sand, and stay near the trail markers so you don’t get disoriented. Check for missile-test closures before you drive out, and consider a ranger sunset stroll.
