Skeleton Coast National Park is a national park located in northwest Namibia, and has the most inaccessible shores, dotted with shipwrecks. The park was established in 1971 and has a size of 16,845 km2 (6,504 sq mi). 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.
