Namibia is defined by emptiness: the dunes of Sossusvlei in the Namib desert, the Skeleton Coast where the desert meets the Atlantic, and Etosha's salt pan where wildlife gathers at waterholes. It is one of the least densely populated countries in the world.
The guides here cover Namibia as a whole. Most trips are self-driven, and gravel roads over long distances are the norm — punctures are common enough that a second spare is standard advice. The dry season from May to October concentrates game at waterholes. Distances between fuel stops are substantial, and mobile coverage disappears across much of the country.
