Oribar-Zahar, Golden sand beach in Orio, Spain.

Oribar-Zahar is a golden sand beach in Orio on the Basque coast, about 200 metres long and 57 metres wide. It lies at the mouth of the Oria river, where the river current meets the Cantabrian Sea and forms a sandbar that shifts with the tides. The beach is backed by a low seawall and the town's riverside buildings.

The beach has been linked to fishing for centuries, as Orio was an important harbor town for the local economy. This maritime past shaped the identity of the coastal community and remains visible today.

Orio's fishing tradition is celebrated each summer during the town's patron saint festivities, when locals carry an image of San Pedro, patron of fishermen, through the streets near the beach. The bars around Oribar-Zahar serve grilled fish and pintxos, and the town's fishing port remains active with boats landing catch daily.

Oribar-Zahar sits just off the GI-638 road at the mouth of the Orio river, a short walk from the town centre of Orio. The beach is reached on foot down a ramp from the roadside parking area, and the sand is fine enough for bare feet. Swimming is best watched against the Cantabrian swell, and the cove is small enough to cross in a few minutes.

The beach hosts surf competitions that draw athletes from across Spain to test themselves on the Cantabrian Sea. These events make it a recognized spot for the sport in the region.
