Arguin is a small island off Mauritania’s Atlantic coast, but the name is often used beside that of the much larger Banc d’Arguin National Park. The distinction matters. The island is one feature within a protected coastal landscape of dunes, shallow water, mudflats and smaller islands; it is not a visitor centre or a single, fully serviced attraction. UNESCO’s record offers a reliable way to understand why this remote shore matters, while current access, transport and visitor arrangements require separate confirmation.
The Banc d’Arguin National Park stretches along the Atlantic coast of Mauritania, between the desert interior and the ocean. UNESCO describes the World Heritage property as 1.2 million hectares, inscribed in 1989 for its natural value. Its landscape combines sand dunes, coastal marshes, small islands and shallow marine waters. Arguin Island is part of the geography that gives the wider park its name, but an article about the island should not imply that every service or activity in the park is located there.
