With the exception of Christmas Day, December 25, the monument is open daily year-round. However, hours of operation vary throughout the year. Please scroll down for a detailed listing of park hours or download a copy of the 2016 monument opening/closing hours.
Operating Hours & Seasons
UNEXPECTED CLOSURES - Especially during the winter and occasionally throughout the year, there are times when the park may have to close due to bad roads or weather. During these times, the website may not contain the most up-to-date information because the website cannot be updated from outside of the park's offices. However, the park does try its best to notify the public. In case of unexpected closures, the information will be available at the following locations in order of priority as soon as possible:
1) Local radio stations KUPR-FM 91.7 and KRWG-FM 90.7
Special Note on Missile Closures: Due to missile testing on the adjacent White Sands Missile Range, it is occasionally necessary—for visitor safety—to close the road into the monument for periods of up to three hours. U.S. Highway 70/82 between Alamogordo and Las Cruces is also closed during times of missile testing. Visitors on a tight schedule are encouraged to call the day prior to arrival to confirm hours of operation.
