Ivory Coast–Liberia border

The Ivory Coast–Liberia border is 778 km (483 mi) in length and runs from the tripoint with Guinea in the north down to the Atlantic Ocean in the south.

It separates the Liberian counties of Grand Gedeh, River Gee, Maryland and Nimba from the Ivorian districts of Montagnes and Bas-Sassandra.

[3] It then briefly follows the Dain, Nimoi and Boan rivers, before reaching the Cavalla, which it follows in a broad right angled course out to the Atlantic.

It ends 21 km east of the southernmost point of West Africa, Cape Palmas.

[5][3] This utilised the Cavalla river and series of straight lines, however the difficulties with demarcating this boundary on the ground led France and Liberia to conclude another treaty on 18 September 1907 (confirmed in January 1911) which moved it southwards to its current position.
