The Camargue, where the Rhône meets the Mediterranean Sea, is the largest river delta in Western Europe. Its vast marshland plains and saline Étangs (brine lagoons) are home to more than 400 bird species including Greater Flamingos. It is also known for its semi feral white horses and fighting bulls.
Arles, the unofficial capital of the Camargue, was an important cultural center for the Romans. Its monuments are part of the UNESCO World Heritage. Gaugin and Van Gogh lived and worked in Arles.
