Place: Banc d'Arguin National Park, Mauritania
Weather: Sunny, 59/77F.
Route: From Saint Louis 665 km north on N2.
Significance: Banc d'Arguin is where the desert meets the sea. The winds bring sand from the Sahara here and have made the sea very shallow. It is a place for birds to migrate to in the winter, where they can feed on fish attracted by the dense plant life in the shallows. Over 100 different bird species come here.
