Sossusvlei (sometimes written Sossus Vlei) is a salt and clay pan[1] surrounded by high red dunes, located in the southern part of the Namib Desert, in the Namib-Naukluft National Park of Namibia.
The name "Sossusvlei" is often used in an extended meaning to refer to the surrounding area (including other neighbouring vleis such as Deadvlei and other high dunes).
The Sossusvlei area forms part of a wider region of the southern Namib Desert with homogeneous features (about 32.000 km²) extending between the Koichab and Kuiseb rivers.
The highest and more stable dunes are partially covered with relatively rich vegetation, which is mainly watered by a number of underground and ephemeral rivers that seasonally flood the pans, creating marshes that are locally known as vleis.
Another important source of water for Sossusvlei is the moisture from the daily morning fogs that enter the desert from the Atlantic Ocean.
Access to the Sossusvlei area of the Namib-Naukluft National Park is from the Sesriem gate, which is located in the surroundings of the eponymous canyon.
The vlei is surrounded by high orange-reddish dunes, partially covered by a vegetation comprising grass, bushes, and some trees (mostly of species Vachellia erioloba).
Since Sossusvlei is possibly the foremost attraction of Namibia, much has been done by the Namibian authorities to support and facilitate tourism in the area.
Numerous places of accommodation are found along the border of the National Park, between Sesriem and the nearest settlement, Solitaire.
It is also possible to take scenic flights over the dunes, either with small planes (mainly from Swakopmund and Walvis Bay) or in hot air balloons (departing from Sesriem in the morning).
The area has been the setting of a number of commercials, music videos, and movies, especially of the fantasy genre; one of the most well-known examples is the psychological thriller The Cell (2000), where the Sossusvlei landscape is used to represent an oneiric virtual reality.
