Gypsum, Not Sand: The dunes are made of gypsum crystals, a mineral that dissolves in water and rarely forms dunes anywhere else on Earth.
A Constantly Moving Landscape: The dunes can shift up to 30 feet per year, meaning trails, landmarks, and even footprints disappear quickly.
Missile Range Closures: White Sands sits within the White Sands Missile Range. The park can close temporarily for missile tests, sometimes with little notice.
Unique Wildlife Adaptations: Many animals here — including lizards, mice, and insects — have evolved lighter coloring to blend into the white dunes.
An Ancient Lake Bed: The dunes formed from gypsum left behind by Lake Otero, a prehistoric body of water that once covered much of the Tularosa Basin.
Indigenous History: The area has been inhabited for thousands of years, with archaeological evidence of early human presence preserved beneath the dunes.
Extreme Desert Conditions: Summer temperatures frequently exceed 100°F, and shade is nearly nonexistent. Visitors often underestimate heat exposure due to the reflective white surface.
Iconic Sunset Light: Sunrise and sunset transform the dunes with pastel pinks, purples, and blues — some of the most striking light in any national park. My photos here are shown from sunset.
Sled the Dunes: Going sledding on the dunes is fun for ANY age. You can pick up a sled + wax at the Store/Visitor Center when you get there for around $30 (if you buy) or you can even rent.
Dog Friendly: White Sands National Park allows dogs throughout the park as long as they are on a leash no longer than 6 feet and under control at all times. Pets are not allowed inside the visitor center or other federal buildings (service animals are permitted). Owners must pick up after their pets and never leave them unattended in vehicles or out of sight. Because the dunes have little to no shade and can get hot during the day, bring plenty of water and plan outings for cooler parts of the day.
