Razo, Golden sand beach in Carballo, Spain.

Razo is a wide, open beach of fine golden sand in the parish of San Martiño de Razo, in the municipality of Carballo, A Coruña. Together with the neighbouring Baldaio beach it forms one of Galicia's largest stretches of sand, facing the Atlantic and backed by low cliffs where fossil beach layers are visible.

Razo's documented history is a record of shipwrecks and pollution reaching its shore: the steamship María Victoria sank here in 1929, the Prestige oil spill arrived in 2002, a military aircraft used the Razo–Baldaio sand as an emergency landing strip in 2003, a merchant ship's cargo washed ashore in 2006, and plastic pellets from a vessel that lost cargo off Portugal reached the beach in 2024.

Razo gives its name to the parish of San Martiño de Razo in the municipality of Carballo. The beach has hosted a surf school since 1991, described as a pioneer in Spain, and volleyball tournaments are held on the sand. Wind conditions also draw hang-glider and paraglider pilots.

The beach has parking, changing rooms, and showers nearby, and lifeguards are on duty during the summer season. Outside those months, conditions can be rough, so it is worth checking the sea and wind forecasts before heading out.

Razo is well known among surfers for its Atlantic swells, which arrive with enough regularity to make it a year-round spot rather than a seasonal one. A section of the beach is set aside for surfing so that swimmers and surfers can share the space without getting in each other's way.
