Beach of Los Quebrantos, Protected coastal area in Soto del Barco, Spain

Los Quebrantos Beach is the only beach in the municipality of Soto del Barco, at San Juan de la Arena. It runs in a straight line for about 810 m with an average width of 100 m, and at low tide joins the Playón de Bayas in Castrillón to form a sandbank some 3 km long. The mouth of the Nalón, Asturias' main river, closes its western end and darkens the sand.

Los Quebrantos is the only beach in the municipality of Soto del Barco, at the mouth of the Nalón, the main river of Asturias. Its dark sand comes from that river mouth, and at low tide it joins the Playón de Bayas in neighbouring Castrillón to form a sandbank about 3 km long. The dune formations behind the beach are badly degraded.

The beach belongs to San Juan de la Arena, a fishing village at the mouth of the Nalón, Spain's main river in Asturias. Its dark sand comes from that river, and the fishing tradition of the village is tied to the estuary rather than to the open beach. The beach is also rated Category-2 for surfing.

The beach has showers, toilets, and lifeguards during summer months plus numerous parking spots near the main road. Visitors will find good orientation and should be careful in rough weather since coastal conditions affect the water.

The area combines a beach, a bird and wildlife protection zone, and a site of community importance for biodiversity all at once. This multiple recognition makes it a special place for nature enthusiasts.
