Banc d'Arguin is one of Africa's great wildlife reserves, a UNESCO World Heritage Site stretching along Mauritania's Atlantic coast between Nouakchott and Nouadhibou. The park protects a vast expanse of shallow coastal waters, sandbanks, and tidal flats where the cold Canary Current meets the desert shore — a combination that makes these waters extraordinarily rich in fish and the feeding grounds they create among the most important waterbird habitats in the world.
The numbers are staggering: an estimated two million migratory shorebirds stop here during the winter, and the park hosts the largest colonies of breeding waterbirds in West Africa, including flamingos, pelicans, spoonbills, herons, and terns. The shallow lagoons support fishing communities of Imraguen people, who have practiced a traditional net-fishing partnership with dolphins here for centuries — the dolphins drive schools of mullet toward the shore while the Imraguen wade in to catch them.
Getting there is not straightforward. There are no paved roads into the park, and access from Nouakchott means driving north over the beach toward Nouamghar, a rough journey requiring a four-wheel-drive vehicle. From Nouamghar you can continue by 4WD or hire a boat to reach the islands and lagoons further north. Most visitors come as part of an organized tour from Nouakchott; independent travel is possible but demands experience with desert driving.
