One of the highlights of the Namib Desert is the huge, red dunes of Sossusvlei. The dunes stand at a height of 300 metres, the highest in the world, and enclose a large clay pan. Wind continually shapes and moves the huge dunes, and it is believed that they originated from sand deposited by the Orange River into the Atlantic Ocean, which moved up the coast and inland to Sossusvlei.
