The Namib Desert, located along the Atlantic coast of Namibia, is one of the oldest and driest deserts in the world, with some areas having gone without rain for over 10 million years. Stretching over 2,000 kilometers, it covers much of Namibia's western region, including the Skeleton Coast and the famous Sossusvlei dunes. The desert is renowned for its striking red sand dunes, some of which reach heights of up to 300 meters, making them some of the tallest in the world. These dunes are composed of fine, wind-blown sand, and their color comes from the high iron oxide content.
