Namibia is renowned for its wide-open spaces, desert elephants and the world's most spectacular sand dunes. With over 15% of the country protected in National Parks and wildlife reserves, Namibia is called "Africa's Gem" and provides its visitors with a wide variety of sights, including shipwrecks on the Skeleton Coast, the sculptured Sossusvlei Sand Dunes of the Namib Desert, the exotic Himba people who still live as nomadic pastoralists in Namibia's least inhabited area of Kaokoveld, and huge gatherings of wildlife at waterholes in Etosha National Park. Namibia is also one of the last places that the San peoples (Bushmen) call home, practicing their hunter/gatherer ways in the remote bush. The climate of Namibia is typically semi-desert, enjoying sunshine year-round; days are hot and nights are cool.
