Dune 45:
Dune 45 gets its name because it lies 45 km past Sesriem (the entrance gate) into the park. It is 80 meters high and it is composed of 5-million-year-old sands.
GPS coordinate: 24.7278° S, 15.4726° E
Sossusvlei:
It is about 66 km past the Sesriem gate. The last 6 km can only be traversed with 4WD vehicles as the gravel road ends and sand begins (the place where the gravel road ends and all non-4WD vehicle must stop there). Sossusvlei is a clay pan, covered in a crust of salt-rich sand.
The river is dry most of the year, and even when it is not, it carries relatively little water to the vlei (a shallow natural pool of water). The vlei is surrounded by high orange-reddish dunes, partially covered by a vegetation comprising grass, bushes, and some trees.

Deadvlei:
Deadvlei is another clay pan, about 2 km from Sossusvlei. A notable feature of Deadvlei is that it used to be an oasis with several acacia trees; afterwards, the river that watered the oasis changed its course. The pan is thus punctuated by blackened, dead acacia trees, in vivid contrast to the shiny white of the salty floor of the pan and the intense orange of the dunes. This creates a particularly fascinating and surrealistic landscape, that appears in innumerable pictures and has been used as a setting for films and videos.

Hiddenvlei:
Hiddenvlei (or Hidden Vlei) is the third most famous vlei in the Sossusvlei area. It is 4 km from the car parking, and it is the least visited.
