Description

The border starts in the west at the Atlantic coast and then goes east, crossing the Langue de Barbarie spit, and then veers north, utilising the Marigot de Mambatio, before reaching the Senegal river. The border then follows this river eastwards in a broad arc, terminating at the Mali tripoint at the Senegal/ Falémé confluence.
