Playa de La Atunara, Coastal beach in La Línea de la Concepción, Spain.

Playa de La Atunara is a beach in La Línea de la Concepción, Cádiz, about 1.5 km long and 90 m wide on average. It lies between the Playa de Levante to the south and Playa de Torrenueva to the north, with some loose stones on the sand. Its dune system is small and degraded by nearby buildings, and the beach is reached by a local road.

Remains of the Tunara battery, a former coastal fortification, stand near the beach as evidence of historical military defense systems. This fortified position reflects the strategic importance of the strait to regional powers centuries ago.

The promenade restaurants along La Atunara are known for pescaitos and the clams of La Atunara. Each year the Virgin of Carmen leaves the port of La Atunara, is carried through the streets of La Línea, and a verbena follows.

The beach has showers, toilets, wheelchair access, and lifeguards available especially during the summer months. Water conditions can vary with the season, so visitors should check local weather before planning a swim.

The dune system behind the sand holds active dunes close to the shore and a wider secondary system where sea lily and sea stock grow; the barrón grass common in nearby dunes is absent here. The natural setting is heavily degraded by nearby buildings and summer crowds.
