Covering 1.6 million hectares, the Skeleton Coast Park remains one of the world's last great wildernesses. Proclaimed in its present form in 1973, it extends from the Ugab River in the south for 500 km to the Kunene River in the north and about 40 km inland. Dense coastal fogs and cold sea breezes caused by the cold Benguela Current add atmosphere to the windswept beaches that are littered with shipwrecks, bones and other debris.
