The landscape is Namibia's defining natural asset. People use all sorts of words to describe it: vast, endless, magnificent, unimaginable, among others. Good words as far as words go, but they don't really do Namibia's top attractions justice. There simply is no frame of reference, nothing that comes close to seeing the sunset at Sossusvlei, spending the day playing at Swakopmund or visiting the Himba in Damaraland.
You have to experience it yourself. And then encourage others to do the same.
