Due to missile testing on the adjacent White Sands Missile Range, it is occasionally necessary to close the Dunes Drive for periods of up to three hours for visitor safety.
Please note that horseback riding is prohibited during all missile tests that affect the monument. Please contact us in advance to verify whether a test has been scheduled for the date of your visit.
The park visitor center and gift shop remain open during missile range closures. Visitors on a tight schedule should contact the park the day before arriving to check on closures at (575) 479-6124.
US Highway 70 between White Sands National Monument and Las Cruces may also be closed during missile testing. For Highway 70 closure information, call the White Sands Missile Range at (575) 678-1178.
