The
Casamance River flows westward for the most part into the
Atlantic Ocean along a path about 200 miles (320 km) in length. However, only 80 miles (130 km) of it are navigable. The Casamance is the principal river of the
Kolda,
Sédhiou, and
Ziguinchor Regions in the northern portion of
Senegal between
the Gambia and
Guinea-Bissau. The three regions are also collectively known as
Casamance after the river.
