Skeleton Coast National Park is a national park located in northwest Namibia, and has the most inaccessible shores, dotted with shipwrecks. The park is 20.000 square kilometres (7.722 sq mi), and possibly the least visited park in the World. The park is divided into a northern and southern section, the southern section is open to those with 4 wheel drive vehicles, they are allowed to go up (north) as far as the Ugab River Gate (where a sign with a skull and crossbones warns you to go no further). The northern section can only be reached by a fly-in safari. The loose sand is a deathtrap to even the most powerful 4 wheel drives.
