Camargue is an extensive river delta of the Rhône, one of the most distinctive and ecologically important wetlands in Europe. It is bordered on the west by the Petit Rhône, which forms the secondary delta known as Petit Camargue, and on the east by the main branch of the river, the Grande Rhône. The entire delta covers more than 930 km², making Camargue the largest river delta in Western Europe.
Geographical Characteristics
Camargue is known for its wide, flat landscapes composed of lagoons (étangs), shallow saline bays and vast marshes. The lagoons are separated from the Mediterranean Sea by long sandy bars and natural ridges formed by the accumulation of river and marine sediments. The area is highly dynamic: river currents, floods, wind and waves constantly reshape the terrain, making Camargue a textbook example of a living, ever‑changing delta.
Ecology and Biodiversity
About one third of Camargue is covered by marshes, saltwater lakes and shallow wetlands that create unique living conditions. The interplay of fresh and salt water, along with extensive reed beds, supports exceptional biodiversity. The most iconic inhabitants are pink flamingos, which nest here—Camargue is the only area in France, and one of the few in the entire Mediterranean, where this species successfully breeds. In addition to flamingos, the delta is home to numerous species of waterbirds, fish, amphibians and insects adapted to saline and marshy environments.
Cultural Landscape
Camargue is not only a natural reserve but also a cultural landscape shaped by centuries of human activity. Along the edges of the delta lie cultivated fields, salt pans, rice paddies and pastures where the characteristic white Camargue horses and black bulls graze. Human intervention through water management, drainage and land cultivation has significantly influenced the appearance of the delta, although its natural dynamics remain the dominant force.
Nature Protection
The central part of Camargue, especially the area around the Étang de Vaccarès lagoon, has been protected as a nature reserve since 1927. In 2008 it was incorporated into the larger Parc naturel régional de Camargue, which aims to preserve natural processes, biodiversity and traditional land use.
Comparable River Deltas in Europe
Although Camargue is the largest delta in Western Europe, several other European deltas are larger or ecologically comparable:

-
The largest river delta in Europe (around 4,000 km²).
-
Exceptionally rich in biodiversity; protected by UNESCO.
-
Extensive marshes, reed beds, canals and lakes.
-
A key breeding area for many bird species, similar to Camargue.
Volga Delta (Russia)
-
One of the largest deltas in the world (around 27,000 km²).
-
A vast network of channels, lakes and wetlands.
-
Important habitat for migratory birds and numerous fish species.
Ebro Delta (Spain)
-
The largest delta on the western Mediterranean after Camargue (around 320 km²).
-
Characterised by rice fields, lagoons and sandy spits.
-
An important area for waterbirds, comparable to Camargue.
Po Delta (Italy)
-
A large delta on the Adriatic Sea (around 380 km²).
-
Marshes, lagoons and extensive agricultural land.
-
Significant bird habitats, especially in the lagoons near Comacchio.
Oder Delta (Germany, Poland)
-
Smaller but ecologically important delta on the Baltic Sea.
-
Wetlands and lagoons such as the Szczecin Lagoon
