Banc d'Arguin National Park is a strictly protected UNESCO World Heritage Site and all visits require advance permission from the Mauritanian park authority. There are no commercial dive operators based in the park. Expeditions are typically organised through Nouadhibou-based operators or international liveaboard charters that secure research or special access permits. The nearest town with dive equipment rental is Nouadhibou, roughly 180 kilometres north. Independent diving is not permitted, and all activities must be supervised by park-approved guides.

The Banc d'Arguin is one of West Africa's most biologically productive marine areas thanks to cold upwelling from the Canary Current. Underwater you can encounter Atlantic humpback dolphins, one of the world's rarest cetaceans, along with green sea turtles, guitarfish, spotted eagle rays, and enormous schools of mullet and bream. The seagrass meadows are nursery habitat for many commercially important fish species. Above the surface, the park hosts over two million migratory shorebirds during winter months.

Conditions are challenging and unpredictable. The bank is very shallow, mostly between five and eighteen metres, but strong tidal currents and variable visibility between five and fifteen metres demand experience. Water temperatures range from 17 degrees in winter to 24 degrees in summer due to the cold Canary Current influence. A 5-millimetre wetsuit is recommended year-round. Winds can be strong, particularly the Harmattan from the Sahara, and surface chop can make boat entries difficult during certain periods.
