Discover Sossusvlei

The Namib Desert has maintained arid conditions for 55 to 80 million years, making it the oldest desert on Earth. While other great deserts have cycled through wet and dry periods, the Namib has remained parched since before the dinosaurs went extinct, its aridity locked in by the cold Benguela Current that suppresses rainfall along the Atlantic coast. This antiquity has created one of the planet’s most specialized ecosystems, where evolution has had tens of millions of years to shape survival strategies found nowhere else, from beetles that harvest fog on their backs to plants that grow two leaves continuously for over a millennium in sand that contains no nutrients.

The dunes of Sossusvlei represent the visible heart of the Namib Sand Sea, a UNESCO World Heritage Site since 2013 covering over three million hectares. These formations began as sediments carried from Africa’s interior by the Orange River, deposited into the Atlantic, then blown back onto land by coastal winds over five million years. The distinctive red-orange color comes from iron oxide coating each grain of sand, the coating deepening with geological age so that older dunes glow a deeper burnt orange than younger formations. Some dunes here exceed 300 meters, ranking among the tallest on Earth, their star shapes sculpted by winds arriving from multiple directions throughout the year.
