Platja Llarga, Golden sand beach in Tarragona, Spain.

Platja Llarga is Tarragona's longest natural beach, a 2,600-metre strip of fine golden sand averaging 33 metres wide, with a gentle slope into the water. A near-continuous band of dunes runs behind it, and rocks at both ends separate it from the beaches of l'Arboçar to the east and dels Capellans to the west.

The shore has preserved its natural character since Roman times when Tarragona served as Tarraco, a major maritime port in the Iberian Peninsula. The coastal formation has remained stable for centuries, shaping the landscape we see today.

The beach lies at the N-340 km 1167 marker and is reached on foot, by car or by public transport; it has parking, restaurants and beach bars. Behind the sand a wetland and dune zone form a habitat protected by the European Union. The Catalan Water Agency tests the water weekly during the bathing season, with excellent results.

The beach offers restrooms, showers, and emergency services with lifeguard coverage from June through mid-September. Visitors can rely on daily water safety support during the peak season.

In 2024 a specific dog area was marked out between the Morrots zone and the tunnel leading to Cala Romana, so dogs are not allowed along the whole 2,600-metre beach.
