Situated in the Namib Naukluft Park, the Sossusvlei is a huge clay pan, guarded by a crescent of giant red sand dunes, an enduring symbol of Namibia. The highest of these dunes is called Big Daddy (sometimes Big Moma!) and is over 300mts high. Climbing to the top is one of the most exhilarating activities to add to your Namibia itinerary. On the rare occasions that it rains in the area, the Sossusvlei fills with water and the resultant turquoise lake is an amazing sight to behold in the middle of the desert!
