Thanks to the great variety of landscapes and the cultural wealth, Brittany is one of the most famous touristic regions in France. Crowds of people, very often concentrated in certain areas at certain times, have become a heavy danger to the whole ecosystem. To avoid the extinction of several species, and recreate a biodiversity in areas that were damaged by overpopulation and natural erosion, Brittany has decided to engage in sustainable development. In order to reconcile tourism with the environment, the Region finances the site remediation of six great protected beauty spots : La Pointe du Raz, the headlands of Erquy and Frehel, marshes of the lower valley of the river Oust,  Ploumanac'h, the Gâvres-Quiberon peninsula and the bay of the Mont Saint Michel.
