Although there is no official U.S. Post Office at White Sands National Monument, both the Western National Parks Association bookstore and the White Sands Trading Company gift shop offer postage stamps of all denominations. You can also mail your postcards and letters via the gift shop's mail box, available just inside the doors leading to the patio.
