Trails in White Sands National Park

White Sands National Park has five established trails, ranging from short, easy walks to demanding routes that lead deep into the gypsum dunes. The Interdune Boardwalk is the most accessible introduction, a half-mile round trip with interpretive stops, benches, and broad views across the interdune landscape. The brief Playa Trail and the one-mile Dune Life Nature Trail offer similarly approachable ways to explore the park’s quieter details, from dry lakebed scenery to the surprisingly resilient plants and animals that survive among the shifting sands. For a more immersive outing, the two-mile Backcountry Camping Trail crosses rolling 40- to 50-foot dunes and rewards hikers with expansive views toward the San Andres Mountains, especially near sunset. The signature challenge is the 4.5-mile Alkali Flat Trail, a strenuous loop through some of the park’s largest dunes. Despite its modest mileage, the constantly soft, loose sand makes every climb count, and the route delivers the rare feeling of being fully enveloped by the vast white dunefield. Hiking here is unlike hiking almost anywhere else: the ground gleams white beneath a huge New Mexico sky, the dunes erase familiar visual cues, and silence settles quickly once you leave the road behind. Trails are marked with colored posts and symbols rather than conventional paths, so route-finding demands attention—particularly in wind or heat. Start early, carry ample water, and treat the dunes with respect; White Sands is at its best when you slow down, follow the markers, and let the landscape’s scale take over.
