You might know gypsum as the white powder inside drywall panels. Gypsum readily dissolves in water, but here it forms sand dunes because no river drains the Tularosa Basin. The white color of the dunes does make for extra intense albedo, so be sure to bring sunglasses and carry plenty of water. Most of the wildlife here is nocturnal, but during the day you may spot a lizard species evolved to camouflage in the sand.

Dunes composed of gypsum make a great destination for snow sledding year round, especially after a rainfall. It is fun to see children wearing T-shirts and shorts sliding down the sparkling white slopes.
Follow markers on the five-mile round trip Alkali Flat Trail that goes up and down dunes with views of the San Andres Mountains.
The white dunes take on the colors of the sunset if you decide to backpack or take the ranger-guided Sunset Stroll.
Spring and fall, since it can be very hot in the summer.
