The wetland is a marsh complex situated along the Mediterranean coast, close to the city of Valencia, which was formed as old lagoons gradually filled with sediments due to longshore drift. It contains three small lagoons, ranging from 0.6 to 6.2 hectares in area, which are fed by fresh water from nearby springs. The Site has a very high biodiversity value, as it contains more than 600 different taxa, as well as a significant number of endemic species. Threatened species are also present, including five plant and 37 animal species. These include Ichthyaetus audouinii (Audouin’s gull) and Valencia hispanica (Valencia toothcarp, locally known as samaruc), the latter being especially important due to its limited distribution and its international critically endangered status. Despite being affected by human settlements, the Site has been little transformed and near-permanent flooding continues, while the coastal strip of the marsh is in a remarkably good state of conservation. The information centre La Casa Penya conducts educational activities.
