Wedged between the Kalahari and the South Atlantic, Namibia boasts deserts, seascapes, bushwalking and boundlessness. Blessed with rich natural resources, a solid modern infrastructure, diverse cultures and an annual quota of 300 days of sunshine, it is a beautiful country of vast potential. Along its entire length, the vast shifting sand dunes of the Namib Desert spread inland for 80 to 130km (50 to 80 miles). In the interior, the escarpment of a north–south plateau slopes away to the east and north into the vast interior sand basin of the Kalahari. In the far northwest, the 66,000 sq km (25,500 sq miles) of the Kaokoland mountains run along the coast, while further inland lies the Etosha Pan (a dried-out saline lake), surrounded by grasslands and bush which support a large and varied wildlife population. The Etosha National Park & Game Reserve is one of the finest in Africa, in that it remains, to a large extent, free of human influence.
