The Étang de Thau (French pronunciation: [etɑ̃ to]; Occitan: Estanh de Taur) or Bassin de Thau is the largest of a string of lagoons (étangs) that stretch along the French coast from the Rhône river to the foothills of the Pyrenees and the border to Spain in the Languedoc-Roussillon. Although it has a high salinity, it is considered the third largest lake in France.
