The Olles Lagoon, lagoon of mirages

The Olles Lagoon (Bassa de les Olles) occupies 54 hectares and is the smallest lagoon in the Ebro Delta Natural Park and also the one that welcomes this so privileged natural setting. These lagoons form a fundamental part of the ecosystems of the Ebro Delta, especially if we consider that it is the largest wetland in Catalonia and the second largest in the Iberian Peninsula.

These coast rafts connect directly with the sea and are surrounded by rice fields, creating a mosaic of incomparable natural textures. In fact, it is the productive cycle of rice that is responsible for marking the tempos of the landscape and nature, as it conditions the oscillations in the level of salinity of the earth, directly affecting the great diversity of flora and fauna that he coexists in the territory.

It seems that The Olles Lagoon is the result of one of the oldest openings of the Ebro. Between rice fields and dunes, and connected directly with the Bay of Fangar, this lagoon is one of the areas with the highest natural wealth and variety of atmospheres of the Ebro Delta.

This scene is the refuge of a significant population of aquatic birds, like the Flamingo, Mallard, Great Egret, Common Kingfisher and Black-Winged Stilt.
