White Sands Hikes: The Best Trails for Every Skill Level

By David Sanchez · Data: National Park Service · ← Complete guide White Sands

White Sands isn't a typical hiking park. There are no forests, no technical elevation gain, and no waterfall waiting at the end of a hard climb. What you'll cross here is 274 square miles of flawless gypsum, where visual landmarks disappear after a few hundred yards. The real challenge isn't altitude. It's navigation and heat.

If you only do one hike, make it the Alkali Flat Trail (4.6 miles round-trip, strenuous). It heads deep into the dunefield to the former bed of Lake Otero, in complete silence. For a first visit or a family outing, the Dune Life Nature Trail (1.0 mile, easy, loop) is enough to get a feel for the park. And if you only have half an hour, the Interdune Boardwalk (0.4 mile, accessible) is an honest introduction to the gypsum dune ecosystem.

How to Prepare for a White Sands Hike

Water and Heat: The Two Rules That Change Everything

White Sands is a true desert. In summer (June through August), afternoon temperatures easily climb above 100 to 104°F. With no shade at all on the trails, the heat feels even more intense. There are no drinking-water stations on the trails, so bring at least 1.5 liters for every hour you plan to hike. Double that amount if you head out after 10 a.m.

The good news is that gypsum, unlike quartz sand, doesn't store solar heat. Walking barefoot remains manageable even in midsummer. That doesn't protect you from heatstroke, though. Start when the park opens at 7 a.m., be back before 11 a.m., or wait until late afternoon. White sand strongly reflects UV radiation, so SPF 50 sunscreen and UV-filtering sunglasses are essential even on cloudy days.

Permits: None for Day Hikes

You don't need a permit for marked day-hike trails. The park entrance fee is all you need: $25 per vehicle (valid for 7 days), $15 per person on foot or by bike, and $20 for a motorcycle. The park's annual pass costs $45. Backcountry camping does require a free permit, issued the same day at the visitor center. There's only one backcountry campsite in the park.

Dogs: Access Limited to Paved Areas

Dogs are allowed in the park but aren't allowed on any unpaved trails. They're permitted on the paved sections of Dunes Drive and in parking areas, on a leash no longer than 6 feet. In hot weather, gypsum can burn their paw pads. In practice, if hiking is part of your plan, leave your dog at your lodging.

Military Closures: An Unexpected Issue to Plan For

White Sands National Park is surrounded by the testing areas of White Sands Missile Range. US Highway 70, the road to the park, regularly closes during missile tests, sometimes for several hours at a time. These closures are unpredictable and aren't announced far in advance. Before setting out on a long trail, check conditions at the visitor center or on the park's official website.

Navigation: Never Leave the Markers

On longer trails such as Playa Trail and Alkali Flat Trail, orange markers stand every 330 to 490 feet. In strong winds, footprints disappear within minutes. Every dune looks alike, and without the markers, you can quickly lose your bearings. Stay strictly between the markers. Don't cut across them, even if the shortcut looks obvious.

The Best White Sands Hikes, Area by Area

All trails start from Dunes Drive, the 8-mile paved road that crosses the park from north to south. They're presented here in order from the entrance to the far end of the dunefield.

The Entrance Area: Introductory Trails

Interdune Boardwalk · 0.4 mile · negligible elevation gain · 20 to 30 min · easy · loop

This trail follows an elevated boardwalk between two dune ridges. It's the only trail that's fully accessible to strollers and wheelchairs. Interpretive signs explain how plants such as dune yuccas and cottonwoods, along with animals such as white-scaled lizards and beetles, have developed genetic adaptations specific to gypsum. It's ideal for a first look or for families with young children. Start at the Interdune Boardwalk parking area, within the first few miles of Dunes Drive.

Dune Life Nature Trail · 1.0 mile · minimal elevation gain · 45 to 60 min · easy · loop

This is the first trail on soft sand. You quickly leave the road and head into the dunes, with 360-degree views across the dunefield from the first ridges. This trail gives you the best sense of the area's silence and strangeness. The loop brings you back to the starting point with little risk of getting lost because the orange markers are well placed. It's perfect for your first hour in the park. Start at the dedicated parking area on Dunes Drive, a few miles past the Interdune Boardwalk.

The Heart of the Dunefield: Playa Trail and Backcountry Camping

Playa Trail · about 5 miles round-trip · little elevation gain · 2.5 to 3 hours · moderate · out-and-back

This trail crosses half the dunefield to reach the playa, a flat white area away from Dunes Drive. The vegetation disappears completely after the first mile, leaving you walking through a pure lunar landscape. The main challenge is physical, with loose sand that slows you down and tires your calves, and thermal, with complete exposure. It's for hikers who are comfortable carrying enough water and gear. Start at the end of Dunes Drive.

Backcountry Camping Trail · about 2.2 miles round-trip · little elevation gain · 1 to 1.5 hours · moderate · out-and-back

This trail leads to the park's only authorized backcountry campsite, deep in the dunefield. For a day hike, it's worthwhile only if you want to explore lightly visited dunes away from the noise of Dunes Drive. To spend the night, you must have a free permit from the visitor center. Start from the same parking area as Playa Trail, at the end of Dunes Drive.

Alkali Flat: The Park's Signature Trail

Alkali Flat Trail · 4.6 miles round-trip · modest cumulative elevation gain from a series of dunes · 2.5 to 3.5 hours · strenuous · out-and-back

This is the trail that captures White Sands at its most intense. It crosses the entire dunefield to reach Alkali Flat, the former bed of Lake Otero, which dried up during the Pleistocene. You arrive on a hardened gypsum floor, cracked and off-white, in complete silence. There are no trees, rocks, or human landmarks visible in any direction. When we visited in October, the low late-afternoon light turned the floor into a matte mirror. The sight alone made the detour worthwhile.

The challenge has less to do with elevation gain, since the dunes top out at about 50 feet, than with fatigue building in the loose sand, full exposure, and the risk of losing your bearings if you leave the markers. Start early in the morning, or no later than 2.5 hours before sunset. The park closes its gates 30 minutes after dark. Water: at least 3 liters per person for the full round-trip. Hiking poles are recommended for descents through deep sand. Start at the end of Dunes Drive.

Easy and Family-Friendly Hikes at White Sands

White Sands is surprisingly accessible for children. The Interdune Boardwalk has no restrictions for a child in a carrier or stroller. On the Dune Life Nature Trail, kids can climb the ridges freely. The gypsum doesn't burn their feet, and the slopes are gentle.

What makes all the difference compared with a typical hike is the heat. Before 10 a.m. outside summer, these two trails are easy to do with children ages 4 and up. From June through August, limit your outing to the hour after opening at 7 a.m., or wait until 5 p.m. Hats, sunscreen, and enough water are nonnegotiable.

For families who want to go a little farther, the first 2 miles of Playa Trail provide a real sense of immersion in the dunefield without requiring the full 5 miles. Turn around when the kids get tired. The White Sands family guide offers additional advice on kid-friendly activities in the park.

Strenuous Day Hikes

White Sands has just one clearly strenuous trail: Alkali Flat Trail. There's no summit to reach and no waterfall at the end. Instead, you'll find something harder to come by: nearly 2.5 miles of deep dunefield with no visible human landmark in any direction.

To get the most out of it, make a few adjustments compared with an ordinary hike:

• Start before 8 a.m. in summer and before 9 a.m. during the shoulder seasons.
• Bring at least 3 liters of water per person for the round-trip.
• Charge your phone and save the parking area's GPS coordinates before you leave. The white sand looks the same everywhere on the way back.
• Hiking poles are useful on descents through loose sand.

Playa Trail is a middle-ground option, at about 5 miles round-trip and moderate difficulty, if you want a real half-day outing without the commitment of Alkali Flat.

Access, Trailheads, and Parking

All White Sands trails start from Dunes Drive, the park's only drivable road. You enter from US Highway 70, 15 miles west of Alamogordo and 52 miles east of Las Cruces. Dunes Drive runs for 8 miles from the main entrance to the end of the dunefield.

The two accessible trails, Interdune Boardwalk and Dune Life Nature Trail, have dedicated parking areas within the first 4 to 5 miles of the road. Playa Trail, Alkali Flat Trail, and Backcountry Camping Trail share the same parking area at the end of Dunes Drive, 8 miles from the entrance.

There is no shuttle in the park. A personal vehicle is the only way to reach the trailheads. Parking is included with the entrance fee. During the busy season, from March through May and in October and November, the parking area at the end of the road fills before 9 a.m. on weekends. Arrive at opening time, 7 a.m., or in the late afternoon.

The visitor center, at the park entrance, is the right place to pick up a backcountry camping permit, check current conditions, and confirm that there are no military closures on US Highway 70. The guide to getting to White Sands explains the options from Alamogordo and Las Cruces.

When to Hike at White Sands

Fall, from September through November, is the most comfortable window, with daytime temperatures of 68 to 79°F, less spring wind, and fewer monsoon storms. Winter, from December through February, is cool in the evening but mild during the day, with very comfortable hiking conditions. Spring is windy. Fine gypsum powder lifted by gusts reduces visibility on the trails and works its way into everything you carry. Summer is manageable only in the first hour of the morning.

The When to Visit White Sands guide covers month-by-month temperatures, seasonal weather conditions, and the dates of the Full Moon Hikes, guided nighttime hikes organized by the NPS on evenings with a full moon.
