The Namib-Naukluft Park is a national park in western Namibia, situated between the coast of the Atlantic Ocean and the edge of the Great Escarpment.
It encompasses part of the Namib Desert (considered the world's oldest desert), the Naukluft mountain range, and the lagoon at Sandwich Harbour.
The best known area of the park and one of the main visitor attractions in Namibia is Sossusvlei, a clay pan surrounded by sand dunes, and Sesriem, a small canyon of the Tsauchab.
With an overall area of 49,768 km2 (19,216 sq mi), the Namib-Naukluft National Park was at the time of its last expansion the largest game park in Africa and the fourth largest in the world.
It consists of a strip of land on the Atlantic Ocean, including 1,609 kilometres (1,000 mi) of sea, that extends roughly 600 kilometres (370 mi) north-to-south from the Swakop River to the B4 road to Lüderitz.
