Platja de l'Auir, Natural beach in Gandia, Spain

Platja de l'Auir stretches about 2.8 km from the mouth of the Vaca river, in Xeraco, to the northern edge of Gandia's coastline, between the beaches of Xeraco and Gandia Nord. It is a narrow coastal strip of fine golden sand with conserved dunes that separates the marjal wetland from the sea, backed by farmland declared non-developable by Gandia's council.

Platja de l'Auir takes its name from a 12th-century irrigation channel (séquia) that crossed rural land in Gandia, Xeresa and Xeraco. Over the years, urban pressure has gradually reduced the beach's size. Today the undeveloped stretch borders farmland owned by the company Rústicas S.A., and the various administrations have worked together on protection and replanting of the area's native vegetation.

Local residents use the beach regularly to swim, play beach sports, and gather with family and friends during warm months. The sandy shore is woven into the daily routine of the community as a place for recreation and socializing.

The beach stretches about 2.8 km from the mouth of the Vaca river, between Xeraco to the north and Gandia's northern beach to the south. Boardwalks cross the dunes to protect native plants, and there is parking, a kite-flying zone and beach-volleyball courts. Red Cross and lifeguard services operate in season.

The shore serves as a stopover point for migrating birds traveling along the Mediterranean coast during seasonal transitions. Birdwatchers visit regularly to observe the different species that pass through the area.
