White Sands National Park
Wind reshapes a brilliant gypsum dunefield where dune crests migrate, plants build pedestals to survive burial, pale animals blend into white sand, and ancient footprints preserve a far older landscape.

White Sands is gypsum, not quartz beach sand. Water dissolves gypsum from surrounding mountains, carries it into the closed Tularosa Basin, and leaves selenite crystals that wind breaks, polishes, and moves northeast into dunes. That ongoing cycle explains the park’s brightness, the firm moist feel beneath the surface, and why dune shapes and routes can change after strong wind.
Dunes Drive provides an easy first look, but walking changes the scale. The Interdune Boardwalk introduces plants and stabilized ground; the Backcountry Camping Trail enters moving dunes; Alkali Flat is the long, exposed route for experienced desert hikers despite its name. Watch for tracks, plant pedestals, ripple direction, and the transition from vegetated margins to the active heart of the field rather than treating the sand as an empty backdrop.
This is a desert visit with unusual hazards. There is little shade, landmarks repeat, summer surfaces are punishing, and missile-range testing can close US 70 and the park with limited notice. Download the NPS map before arrival, set a turnaround time, keep the next route marker in sight, and choose a gentle dune with a flat runout if sledding—never aim toward roads, vegetation, or a hard interdune floor.

Good to know
Check the NPS closure page on the day of travel: missile testing can close both the park and US 70, and the gate schedule changes seasonally. Cell service is unreliable, so save the NPS map offline and download or print an entrance pass before arrival; there is no fuel, full restaurant, or overnight campground inside the park.
