White Sands National Park, in the Tularosa Basin of southern New Mexico, protects the world's largest gypsum dunefield — great wave-like dunes of brilliant white sand spread across 275 square miles of desert. The National Park Service manages this surreal landscape, where the rare gypsum sand stays cool underfoot even in summer heat. A scenic drive loops into the heart of the dunes, making it an unforgettable stop on a southern New Mexico RV route.
Best season — Fall through spring (milder desert temperatures); check NPS hours and closures

On the ground
The gypsum that forms these dunes is unusual: it rarely survives as sand because it dissolves in water, but the closed Tularosa Basin traps it, leaving wave after wave of soft white sand reflecting the desert sky. The effect is otherworldly, especially in the long light of early morning and late afternoon.
Because the park borders an active military range, the entrance road can close temporarily for testing, and hours vary through the year. The white surface also makes the dunefield feel cooler and brighter than a typical desert, which shapes the best times of day to explore.
Check current hours, any testing-related closures, and camping options on the National Park Service site before you plan your route, since access here depends on more than just the weather.
