Las Médulas is the municipality of Borrenes’ main tourist attraction: a landscape shaped by Roman gold mining, whose traces extend far beyond individual viewpoints. Mining began in the 1st century AD and was carried out using the power of water. In December 1997, Las Médulas was added to the UNESCO World Heritage List. When planning your trip, it is worth distinguishing between three perspectives: the extensive mining landscape, the archaeological sites within the municipality, and the routes through the natural monument.
Las Médulas as a mining landscape
The archaeological zone of Las Médulas covers more than 2,000 hectares. It includes mines, spoil heaps, reservoirs and canals. These features reveal different aspects of historical mining and help explain why Las Médulas is viewed not as a single site, but as an extensive archaeological landscape. The Archaeological Park extends across Borrenes, Carucedo and Puente de Domingo Flórez. When arranging places to visit during your stay, this regional perspective helps distinguish the sites within Borrenes from other points in the park.
The Mirador de Las Médulas in Orellán offers a striking view of the ravines and rock pinnacles. From there, an access route leads to the Galería de Orellán, where you can see the inside of this Roman engineering structure. Check current access arrangements before your visit. This allows you to treat the viewpoint as a separate stop without confusing it with the archaeological sites within the municipality.
Archaeological traces in Borrenes
The archaeological heritage area of Las Médulas includes El Castro o La Corona del Cerco de Borrenes and the Castrelín de San Juan de Paluezas; both are located within the municipality of Borrenes. The Castrelín is an Asturian hill fort on a promontory above the Sil. It offers views over the river plain and far across El Bierzo. The Castro de Borrenes dates to the final phase of the local population’s independence from Roman rule. Its impressive wall is particularly noteworthy. The Castro is also considered evidence that the arrival of the Romans was not a peaceful event for the native population.
Another site linked to mining is the Asentamiento Metalúrgico de Orellán. It was founded under Roman rule and inhabited by local people who worked in the mines. The municipality highlights this settlement and the Castrelín as two of its five places to visit in Las Médulas. Together, these sites offer different insights into the region’s history, from life before and during Roman rule to work in the mines.
Loop route, viewpoint and longer trail
The L1 Senda Perimetral is a 10.5-kilometre circular route through the Las Médulas natural monument, which can be completed on foot or by bicycle. It passes through Borrenes, Carucedo and Puente de Domingo Flórez. Orellán is the recommended starting point; there are additional access points at the Casa del Parque de Carucedo. After climbing from Orellán, the route leads to the Canal de Peña Escribida. The Senda Perimetral is also suitable for mountain biking. As trail conditions can change, check them before setting out.
The Camino de Santiago de Invierno is a much longer route that passes through the municipality of Borrenes. The full route between Ponferrada and Santiago de Compostela is 258 kilometres long and consists of nine stages. One particularly scenic route passes through Priaranza and Cornatel Castle, descends towards Borrenes and eventually leads to Las Médulas. The Camino’s length and number of stages clearly distinguish it from the Senda Perimetral loop. At the entrance to Borrenes stood the Casa Hospital de Peregrinos from the 16th century onwards. Around 1580, the Merindad de Cornatelo founded the pilgrims’ hospital to care for travellers on their way to Santiago; it was abandoned at the end of the 18th century.
Chestnut culture and local festivals
The Aula del Castaño is located in the former school building in Borrenes. This themed centre explores the history of the chestnut and its spread across El Bierzo. Historically, chestnuts played a role in food and trade in the region and its surroundings. This subject connects a specific place in Borrenes with the wider cultural history of the region. Language and festivals also shape the area’s local character: Galician is regularly spoken by residents. In Borrenes, festivals are held in January in honour of San Vicente, on the first Sunday after Easter in honour of the Virgen de la Vega, and in June in honour of San Antonio.
