Soto del Barco, Asturias: municipality guide
Soto del Barco is a coastal municipality in central Asturias, at the mouth of the river Nalón: 3,801 inhabitants on 40.23 km². Its capital is the town of Soto del Barco. Between the largest estuary in the Principality and the Cantabrian Sea, it combines the seafaring tradition of San Juan de la Arena with the monumental heritage of San Martín Castle and dark-sand beaches such as Los Quebrantos.
What to see in Soto del Barco
San Martín Castle is the great emblem of the municipality: a medieval fortress commissioned by Alfonso III on the site of an ancient hillfort, on a headland overlooking the mouth of the Nalón. From its walls you can see the estuary, the port of San Juan de la Arena and, in the distance, the Cantabrian Sea.
Los Quebrantos beach, also known as El Pozaco, is a dark-sand beach more than a kilometre long next to San Juan de la Arena, popular for walking and surfing. The fishing town of San Juan de la Arena keeps its fish market, the old Lis cannery and the Puerta del Mar interpretation centre, devoted to fishing and the history of the port.
Inland, the Ferrera Palace in Ponte is a 16th-century manor house linked to one of the most powerful families of early modern Asturias, and the La Magdalena Palace completes the municipality’s civil heritage. The Nalón estuary, with its marshes and its mouth between Soto del Barco and Muros de Nalón, is also an area of great natural value, a refuge for birds and boats.
Camino de Santiago: the Camino del Norte, an official Jacobean route declared a UNESCO World Heritage Site, crosses the municipality through Ranón and El Castillo on its stage towards Muros de Nalón.
Getting there
The A-8 motorway (Autovía del Cantábrico) gives access to the municipality, located between Avilés and Cudillero. The coastal N-632 road runs along its seafront and the FEVE railway has a station in Soto del Barco, with connections to Avilés, Oviedo and western Asturias.
Festivals and gastronomy
The main festivals are those of San Telmo and San Juan, on 24 June, in San Juan de la Arena: their seafaring procession is declared a Festival of Tourist Interest of the Principality. The festive calendar includes San Isidro and San Pedro in the capital, San Blas and Nuestra Señora in Riberas, San Roque in Ranón, San Lorenzo in La Corrada, San Martín in El Castillu and the Sagrado Corazón in Caseras. At the table, seafaring cuisine rules, with elvers —fished in the municipality itself— as the star dish, alongside fish from the daily catch and Cantabrian shellfish.
