The Namib is a coastal desert in southern Africa. The name Namib is of Nama origin and means "vast place". According to the broadest definition, the Namib stretches for more than 2,000 kilometres (1,200 mi) along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa.
The Southern Namib desert is home to some of the tallest and most spectacular dunes of the world, ranging in color from pink to vivid orange. These dunes continue right to the edge of the Atlantic Ocean. The cold waters of the sea brushing against the dunes of the Namib desert is one of the most surreal sights.
The Namib Desert is often referred to as the world's oldest desert and has been in existence for some 43 million years, remaining unchanged in its present form for the last 2 million years. The Namib is an immense expanse of relentlessly moving gravel plains and dunes of all shapes and sizes that stretch along the entire coastline. The most widespread and dominant type of desert sand dune are linear dunes, with crescent shaped dunes common along the coast and clusters of star dunes, such as the towering horseshoe of dunes at Sossusvlei, found in the eastern reaches of the sand sea.
