Playa de Merón, Sandy beach in Villaviciosa, Spain.

Playa de Merón is a sandy beach in Villaviciosa on Spain's northern coast, featuring a substantial shoreline with fine sand. Rocks and geological formations frame the water's edge, creating a natural boundary between beach and sea.

The beach lies at the mouth of the Merón River, between the parishes of Argüero and Careñes, 14 km from Villaviciosa. It forms part of the Asturian Jurassic Coast, a stretch of coastline catalogued as a Site of Community Importance (LIC) for its geology. The sources record no dinosaur tracks or other prehistoric finds at the beach itself.

The beach lies at the mouth of the Merón River, on the boundary between the parishes of Argüero and Careñes, 14 km from Villaviciosa. It forms part of the Costa del Jurásico Asturiano and of the eastern coast of Asturias, and is catalogued as a Site of Community Importance (LIC).

Visitors can reach the beach via local roads that lead to a parking area for vehicles. From there, access to the shoreline is straightforward and requires only a short walk without major obstacles.

Where the Merón River meets the sea, the waters create visibly different colorations that become particularly noticeable at low tide. This natural phenomenon surprises many visitors and reveals how freshwater and saltwater interact at their meeting point.
