If you're an even more committed nature lover, venture into this intensely protected area at the very heart of the Camargue, where a central pond called Le Vaccarès is mostly used as a site for approved scientific research. The wildlife (birds, nutria, fish) is virtually undisturbed here, and you won't come across the cabins and herds of bulls and horses found elsewhere in the Camargue. Made up mostly of vast ponds and marshland, access to this area is limited to horseback, bike, and foot. Paths around its perimeter permit views of the birds and other wildlife. Maps detailing these paths can be downloaded from the Parc Naturel Régional de Camargue website. They're also available from tourist offices in Arles, Stes-Maries-de-la-Mer, and Port Saint-Louis, as well as bike rental shops in Stes-Maries-de-la-Mer.
