7. Sossusvlei Namib Desert National Park, Namibia
Located in the Namib Naukluft Park, the Sossusvlei Namib Desert National Park is a large salt and clay pan, guarded by huge red sand dunes, a popular symbol of Namibia. Big Daddy is the highest of the red sand dunes and it is over 300 meters high. One of the most exciting activities to try is to climb to the top of Big Daddy. During exceptional rainy seasons, the Sossusvlei fills with water and the turquoise lake is a fantastic sight to see in the middle of the desert.
