From the Estuaire car park, you will walk along the Slack to its mouth. Amid the pebbles, you might catch a glimpse of the plovers building their nests, or the sea kale. From the Les Allemands car park, you'll discover the beach with a clay cliff where swallows nest. On the other side, you'll find the immense sand dunes (over 200 ha of dunes, one of the largest in the department), dotted with pools in which various amphibians come to breed.
