White Sands
📍 Tularosa Basin, near Alamogordo, New Mexico, USA
The largest gypsum dunefield on Earth — 710 km² of brilliant white dunes in New Mexico's Tularosa Basin, protected in White Sands National Park and surrounded by a missile range.
What makes it marvelous
White Sands National Park protects the southern 41% of a 710 km² field of white sand dunes made of gypsum crystals — the largest gypsum dunefield on Earth. The dunes stand up to 18 metres high on a sand sheet about 9 metres deep, holding some 4.1 billion tonnes of gypsum. Around 12,000 years ago the basin held large lakes; as the climate warmed and dried, the lakes evaporated and left selenite crystals, which the wind broke up and carried east as sand — a process that still goes on. Several animals here have evolved white or pale colouring, and at least 45 species live nowhere else, 40 of them moths.
Why visit
Walk, sled or sit on dunes as white as snow — and watch the sand turn pink and blue as the sun goes down behind the San Andres Mountains.
Still deciding?
White Sands comes up most often against one other place — each one weighs cost, effort, season and crowds side by side.
What to know before you go
🗓️ Best time
Spring and autumn are mild; summer days are very hot and winter nights cold. Sunset and the hour after are the best time on the dunes.
🧭 Getting there & access
From Alamogordo, about 13 miles (21 km) along US-70 to the visitor centre, then the 8-mile (13 km) Dunes Drive into the dunefield. The road can close for up to three hours during missile tests on the surrounding range.
Good to know
- Check the park's closures page before you go — missile tests can shut Dunes Drive for up to three hours.
- Fill up with fuel in Alamogordo; there is none in the park.
- Carry plenty of water and note landmarks — every dune looks the same and the white sand reflects heat and glare.
- Bring or buy a plastic sled; the steeper dune faces make the best runs.

White Sands looks like snow until you touch it. In New Mexico’s Tularosa Basin, a field of dunes covering about 710 km² is made not of quartz but of gypsum — the largest gypsum dunefield on Earth — and the sand stays cool and bright even under a desert sun.
It formed when the climate changed. Around 12,000 years ago the basin held large lakes, streams and grassland. As it warmed, rain and snowmelt dissolved gypsum from the surrounding mountains and carried it down into the lakes; as they dried, the gypsum crystallised as selenite, and strong winds broke the crystals up and drove them east as sand. The process continues today. The dunes reach 18 metres high on a sand sheet about 9 metres deep.
Life here has adapted to the white: several animals have pale or white colouring, and at least 45 species — 40 of them moths — live nowhere else. White Sands National Park protects the southern 41% of the dunefield; the rest lies inside White Sands Missile Range, which is why Dunes Drive sometimes closes for tests. Bring a sled, plenty of water, and stay for sunset, when the dunes turn pink and then blue.
