Namib-Naukluft National Park stretches across a vast part of western Namibia, between the Atlantic coast and the escarpment inland. The Ministry of Environment, Forestry and Tourism lists its area at 49,768 square kilometres. It is not one uniform dune field: the park contains parts of the Namib Desert, the Naukluft Mountains, gravel plains, ephemeral rivers, coastal environments and the better-known visitor landscapes around Sesriem and Sossusvlei. Distances between these areas are substantial, so a map pin should not be mistaken for a short day trip.
The Namib Sand Sea, a UNESCO natural World Heritage property, lies wholly within Namib-Naukluft Park. UNESCO describes it as a coastal fog desert with extensive shifting dunes. Wind, rivers and ocean currents transport sand from far inland, while fog provides the primary source of water for specially adapted plants and animals. The desert is therefore not simply a backdrop of orange dunes: it is a dynamic system shaped by air, water and geology, with life adapted to extreme aridity.
