Sant Antoni, Golden sand beach in Cullera, Spain.

Sant Antoni is a beach of fine golden sand at the end of Avenida Diagonal, facing the Parque de San Antonio in Cullera's San Antonio de la Mar neighbourhood. It runs for about two and a half kilometres with a width of 75 metres, and the water stays shallow far out, so bathers must wade a long way before it covers them. At the far end, a rocky breakwater separates the sand from the mouth of the Júcar, and the small Peñeta del Moro islet with its little lighthouse stands offshore.

The beach received Blue Flag certification decades ago, marking the start of its formal recognition for environmental and safety standards. This designation led to sustained investment in the beach's infrastructure and management practices.

The beach sits within a neighborhood where traditional Valencian cuisine defines the dining scene, reflecting centuries of Mediterranean fishing heritage. Visitors experience this food culture directly, with local restaurants preparing dishes that connect to the community's relationship with the sea.

The beach is closed from 5:00 to 8:00 for cleaning, so plan swimming outside those hours. Its fine golden sand shelves very gradually, letting small children wade far out before the water covers them. Access is adapted for people with reduced mobility, and a rocky breakwater at the far end separates the sand from the mouth of the Júcar and the river port.

The beach sits just a short walk from Cullera's center, allowing visitors to move easily between beach time and exploring the town. This proximity makes it a place where one can enjoy both sea and city life throughout a single day.
