The Gallocanta Lagoon is located at the bottom of a large basin that results from karst corrosion in a polje, and is in the Zaragoza region of Campo de Daroca . This basin is closed and covers an area of about 53,000 hectares, and the bottom of the lagoon has an altitude of about 1,000 meters above sea level, with a depth of less than 3 meters.
It has such beauty that it seems that the lagoon is a perfect sheet of water over the basin, and when there is a drought for a long time that sheet disappears almost completely until the water and moisture return. This entire area is divided into 3 areas: the Lagunazo de Gallocanta, the Lagunazo Grande and a mosaic with small reed beds, meadows and lagoons.
This beautiful lagoon is salty and among its vegetation you can find many very valuable and some of them even in danger of extinction, such as the Puccinelia Pungens or the Lythrum Flexuosum, both plants that adapt perfectly to very saline environments . The salt becomes concentrated in almost 105 grams / liter, so there are no fish since they could not survive in such a salty environment.
As for the fauna, you can get to see more than 200 different species of birds, both wintering and passing through or nesting. Those that stand out the most are the aquatic birds and steppe, such as the Common Crane , of which there are more than 70,000 birds.
In the Laguna de Gallocanta area there are several places of interest to be able to enjoy more of the environment, such as the Observatorio de los Aguanares, the Observatorio del Cañizar , the Mirador de Berrueco, the Museo del Hombre, the Laguna de La Zaida or the Laguna of Guialguerrero.
