The Namib-Naukluft National Park is the largest national park in Africa and the Namib desert is the oldest desert on earth. It features Sossus vlei, a dry clay pan, which is seldom filled with water. The average rainfall is 50 mm/year. Dead vlei is renowned for its fossilised thorn trees with its eerie atmosphere. The sand dunes with their brilliant colours are of the largest sand dunes in the world reaching up to two hundred metres. The orange colour is due to iron in the sand is oxidized over time
