White Sands National Park protects the largest gypsum dune field on Earth, a rippling sea of brilliant white sand covering nearly 150,000 acres of the Tularosa Basin in southern New Mexico. Unlike typical desert sand, gypsum crystal stays cool underfoot even on warm days and reflects light so brightly that the dunes can look almost like snow, a genuinely strange and beautiful landscape unlike anywhere else in the National Park System.

Best Things to Do at White Sands

Sled Down the Dunes

Sledding is the park’s signature activity, and plastic snow sleds, sold at the visitor center, glide surprisingly well over the fine gypsum sand. Finding a steep, well-packed dune away from the main crowds tends to produce the best runs, and it’s an activity that works for nearly any age or fitness level.

Drive Dunes Drive at Sunset

The park’s main road winds eight miles into the heart of the dune field, and driving it in the late afternoon as the low sun turns the white sand shades of pink and gold is one of the most rewarding ways to experience the park without much physical effort.

Hike the Alkali Flat Trail

This longer, more demanding trail loops across five miles of open dune field with only backcountry marker posts to guide the way, a serious undertaking without shade but a genuine immersion into the scale and isolation of the dune field for visitors comfortable with desert hiking.

Walk the Interdune Boardwalk

A shorter, accessible boardwalk trail near the visitor center introduces the park’s ecology, including plants and animals uniquely adapted to life in gypsum sand, making it a good option for visitors with limited time or mobility.

Join a Ranger-Led Sunset Stroll

Seasonal ranger programs guide small groups out into the dunes to explain the geology and wildlife of the gypsum field while timing the walk to catch the sunset, adding context that’s easy to miss exploring on your own.

Best Time to Visit

Spring and fall bring the most comfortable daytime temperatures for hiking and sledding, while summer afternoons in the Tularosa Basin get intensely hot with almost no natural shade anywhere in the dune field. Sunset is consistently the best time of day here regardless of season, when the sand’s color shifts dramatically and temperatures cool off.

How to Get There

White Sands National Park is located near Alamogordo in south-central New Mexico, reached by car via US-70, and it sits close enough to nearby missile range operations that the highway occasionally closes for testing, so it’s worth checking road status before a visit. There’s no public transit to the park, making a personal or rental vehicle the standard way to arrive.

Good to Know

  • Sand sleds and wax to help them glide are sold at the visitor center gift shop; bringing your own snow sled also works.
  • There are no reliable landmarks once you’re out among the dunes, so stay near marked trails or your vehicle to avoid getting disoriented.
  • Shade is essentially nonexistent, so sun protection and extra water are essential even for a short visit.
  • The visitor center has exhibits on the dune field’s formation and the surrounding basin’s unusual ecology, worth a stop before heading into the dunes.

White Sands offers a landscape that photographs like snow but behaves entirely like a desert, and that contradiction is exactly what makes it worth the detour. Whether you’re sledding down a dune or simply watching the light change at sunset, it’s unlike any other stop on a Southwest road trip.
