Earth's Incredible Places: Sahara

Touching every corner of North Africa is the Sahara Desert, one of the wildest habitats on Earth. This is a land of singing sand dunes, barren plains, mirages and glistening oasis pools. Against all odds, life manages to thrive here. Discover river crocodiles, scorpions and foxes, ancient pharaohs, nomadic tribes and camel caravans. With its scorching hot days and night-times that dip below freezing, the Sahara is a land of extremes, where only the tough survive.
