Border Crossings Between Mauritania and Senegal

You meet two Sahel countries along a 742 km border that follows the Senegal River from the Atlantic in the west to the Mali tripoint in the east. Senegal and Mauritania share this watery frontier with two main crossings: the busier Rosso post and the calmer Diama dam route through Djoudj National Park. The river once fueled disputes but now supports regular trade and herding movement.

You choose Diama for fewer crowds and a park drive or Rosso for direct highway access, though both require patience with fees and checks. Dry season offers stable conditions; rains can impact unpaved approaches to Diama. Carry ouguiya or CFA francs and organize vehicle papers if driving. After crossing you reach Saint-Louis in Senegal or continue toward Nouakchott in Mauritania. Monitor ferry or dam status before travel.
