This national park was created in Mauritania on 24th June 1976 and declared a UNESCO World Heritage Site in 1989. It covers approximately 65 km of coastline, and extends around 30 km to the interior. The most representative fauna are cormorants, gazelles and hyenas. It also has a rich archaeological heritage, in particular shell middens, in some cases several kilometres long and tens of metres high.

The preservation of biodiversity in the low Delta and the valorisation of the cultural features of its indigenous peoples are among its main objects.
