Visitors are free to roam over any area within the park, but should avoid walking on the crypobiotic crusts of the inter-dune areas. Entering the White Sands Missile Range is not allowed, so be aware of your location. Marked trails include:

 • Playa Trail (0.2 mile / 0.3 km round-trip). A very short trail to a dried lakebed.
 • Big Dune Trail (1 mile / 1.6 km round-trip). A self-guided nature trail.
 • Interdune Boardwalk (0.4 mile / 0.6 km round-trip). A wheelchair-accessible nature trail.
 • Alkali Flat Trail (4.5 mile / 7.2 km round-trip). A backcountry trail through the heart of the dunes. This trail is marked by posts with orange tape on them and may be difficult to follow for inexperienced hikers. In addition, there is a monthly ranger-led hike to Lake Lucero (located in the Missile Range). The cost is $3 per person, and the round-trip takes three hours. Reservations are required and can be made by calling (505) 479-6124 or (505) 679-2599. The tour schedule is posted online, and is also available from the visitor center.

Dune-sledding

Some of the dunes are tall and steep enough to provide a good ride on a plastic toboggan or sled. While some visitors attempt sledding on everything from cardboard boxes to garbage bags, you'll want to bring your own sled for the best experience.

Stargazing

During the summer and early Fall the park service has Friday Night Star Talks on most Fridays.

Photography

Dune photography is best in the morning and evening when the sun is low on the horizon, producing interesting shadows on the dunes. Camera meters may be fooled by the white sand, so it is a good idea to meter slightly higher than what is reported by the light meter to avoid having the sands appear grey.
