Namibia is one of the safest countries in Africa for camping. Wildlife is concentrate near to big rivers or in National Parks and there is almost no delinquency. Also is a very dry land, practically the whole country is a desert so that means that is a perfect place to see the milky way at night. In the South when you ride parallel to Orange river you can find river beds that in dry season are completely empty of water and is a perfect place for set your tent and pass a quiet night during you trip.
