The Delta del Ebro, with an area of 125 square miles, is the biggest marshland in Catalonia and on the Mediterranean coast of Spain.

It is the second biggest marshland in the western Mediterranean Sea, after the Rhone delta, in southern France. The delta is a totally flat landscape covered with rice fields that keep changing colour through the seasons: earth coloured in the winter, water that reflects the colours of the sky in the spring, green in the summer, yellow tones in September…

Every year, when October and November arrive, more than 60,000 birds from almost 300 different species meet at the Delta del Ebro to nest and to spend the winter there. Flamingoes, herons, eaglets, owls, cranes and hundreds of kinds of ducks come to the delta attracted by the water and the warm climate, and turn the final section of the river Ebro into one of the most unique landscapes in Europe.

The Ebro estuary is relatively young: it was formed between 14th and 18th centuries, and every year, thanks to the sediments that the river drags down with it, it gets bigger. The delta is 20 miles long and has a shape similar to the Greek letter delta (D), as happens in some big estuaries: in fact it is because of this that the Greeks gave this name to estuaries.
