Black Desert located approximately 50 km to the South of Bawiti. The mountains have eroded to coat the desert with a layer of black powder and rocks giving it its name. Towards the end of the Black Desert are black volcanic hills that ages ago erupted a dark volcanic material called dolerite, which is what the black rocks are made of.

Agabat is a small valley of unusually beautiful mountain formations. Here, the white cliffs common to the White Desert meet the dunes and the yellow limestone rocks of Sahara.

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.
