Flix (Catalan pronunciation:[ˈfliʃ]) is a town in the comarca of Ribera d'Ebre, Catalonia, Spain. Situated on a promontory by the Ebro river, the town occupied an important strategic position. Situated on the Madrid–Barcelona railway line, it expanded in the early twentieth century with the construction of a hydroelectric power station in 1948 and a large chemical plant, Electroquímica de Flix.
One of the main tourist attractions is fishing in the horseshoe-shaped bend in the river. Every year there is a large international fishing competition in Flix.
The Ebro (Spanish and Basque [ˈeβɾo]; Catalan: Ebre, Western:[ˈeβɾe], Eastern:[ˈeβɾə]) is a river of the north and northeast of the Iberian Peninsula, in Spain. It rises in Cantabria and flows 930 kilometres (580 mi), almost entirely in an east-southeast direction. It flows into the Mediterranean Sea, forming a delta in the Terres de l'Ebre region, in southern Catalonia. In the Iberian peninsula, it ranks second in length after the Tagus and second in discharge volume, and drainage basin, after the Douro. It is the longest river entirely within Spain; the other two mentioned flow into Portugal.
