Beautiful view of the Marais Vernier natural site. I had, when I was 18, the honor and the pleasure of working there in the company of several biologists. It is an exceptional site due to the richness of its fauna. On site live Camargue horses, Hyland cattle, Scottish sheep, gray herons and many other species. A few group visits are regularly organised. To participate, you must register in advance on the Marais Vernier nature reserve website.
