Roman Channels. From the Aquilianos to Las Médulas.

The system of channels collected water from the Montes Aquilianos and other surrounding mountain ranges (even having one channel, the C3, with a length of 143 kilometers) and transported it to the reservoirs located at a higher altitude above the gold deposit. Once there, the water was used through the ruina montium system, which consisted of accumulating it and releasing it under high pressure to collapse the alluvial mountains and extract the gold, evacuating the waste toward the valleys.

Walking along the remains of these channels is a fascinating experience that combines hiking, history, and geology. The route allows visitors to walk next to the trenches carved into the rock by the Romans, admire tunnels such as the Espernada Tunnel in Corporales, and enjoy spectacular landscapes, contrasting Roman engineering with the natural beauty of El Bierzo.

Activities and Routes

Several trails follow the path of the ancient channels, suitable for hiking and often for the whole family.

• Popular Routes: They include sections of the GR-292 and marked trails that connect with Las Médulas. Detailed information about the different channels (C1, C2, C3, etc.) and their respective trails can be found on specialized websites.
• Guided Tours: Local companies offer guided tours that explore the history and operation of this complex hydraulic network in depth.
• Schedule and Fees: Access to the trails is free and open all year round, 24 hours a day. Guided tours have a cost and require prior reservation.
• Accessibility: The routes are generally not accessible for wheelchairs due to the nature of the terrain (mud, stones, slopes), so the use of baby carriers is recommended and caution is advised along the path.

♿ Accessibility

The routes through the Roman Channels from the Aquilianos to Las Médulas are not accessible for wheelchairs or people with reduced mobility.

Access to these trails is a hiking activity and the terrain conditions prevent accessibility:

• Irregular terrain: The trails are mountain and rural paths with rocky sections, slopes, and natural unevenness that do not allow wheelchair circulation.
• Historical nature: The channels are works of ancient engineering carved into rock or supported on masonry walls that were not designed with modern accessibility standards.
• Tunnels: The famous Espernada Tunnel in Corporales can be crossed on foot but is not accessible for wheelchairs.

Accessible alternatives in the Las Médulas area: Although the channels are not accessible, the environment of the Natural Monument of Las Médulas does have options for people with reduced mobility:

• Accessible trail of the Lago de Carucedo: a circular route between the park house and the shores of the lake designed to be accessible.
• Mirador de Orellán: the access to the main viewpoint offering the most famous panoramic views of Las Médulas usually has adapted accessibility.
• Adapted transport: accessibility plans have been implemented that include adapted transport to certain points of interest.
