These sculptural formations are best viewed at sunrise or sunset, when the sun lights them with orangey-pink hues, or under a full moon, which gives the landscape a ghostly Arctic appearance. The sand around the outcroppings is littered with quartz and different varieties of deep-black iron pyrites, as well as small fossils. On the west side of the Farafra–Bahariya highway, away from the wind-hewn sculptures, chalk towers called inselbergs burst from the desert floor into a spectacular white canyon. Between them run grand boulevards of sand, like geologic Champs-Élysées. No less beautiful than the east side of the road, the shade and privacy here makes it a great area to camp.
